Bone can heal small defects by itself but fails to do so in case of severe bone damage. A common treatment for severe damage is grafting bone. Approximately 1.6 million bone grafts are performed in the United States per year [1]. Unfortunately, this treatment has several serious drawbacks, such as a high risk of infections or even donor site morbidities. Tissue Engineering and regenerative medicine is a promising biomedical alternative to cure severe bone damage. Scaffolds can be used to re-build the bone structure since they can support seeded cells and provide an optimal environment for cell growth [2]. The scaffold{\textquoteright}s geometry design influences flow characteristics, mass transfer rates, and wall shear stress (WSS). The WSS is an important parameter to investigate because it affects the differentiation and bioactivity of cells inside the scaffold. In this work, we investigate the influence of the scaffold geometry on the flow field, WSS and mass transport using computational fluid dynamics (CFD). The reliability of the numerical results is evaluated using the μ-particle image velocimetry (PIV) method.

Bone is one of the most transplanted tissues. About 1.6 million bone grafts are performed each year only in the United States [1]. This treatment has serious drawbacks, such as a higher risk of infections or even donor site morbidities. Therefore, an alternative is the use of scaffolds to create bone tissue. The role of scaffolds in bone tissue engineering is to mimic the native bone tissue and is used to provide a template that supports seeded cells to get an optimal environment for their proliferation [2] to re-build the damaged structure. Hence, an optimal scaffold design is important and must be found because even small changes in the geometry of the pore network of the scaffold influences the process of cell growth and mechanical properties [2,3]. Wall shear stress (WSS) has a significant role in the differentiation of cells, especially for bone. Even minor changes in the flow field, especially near the wall regions, can directly affect cell bioactivity. Therefore, in this work, we use computational fluid dynamics (CFD) simulations to investigate the WSS and the effect of the flow rate on mass transport rates in scaffolds. The numerical results were compared to {\textmu}-particle image velocimetry (PIV) experiments to evaluate the reliability of the CFD method.

Slow pyrolysis of biomass is commonly performed in rotary kilns. The effect of the particle residence time distribution on biomass conversion is often neglected when numerically modeling such systems. But this effect might be significant under certain conditions. The data presented here are results of numerical simulation of the biomass pyrolysis in rotary kilns under numerous operating conditions and levels of axial dispersion of biomass particles. The varied operating conditions are the kiln diameter (D=0.1{\textendash}1\ m), the ratio of particle to kiln diameter (d/D=5{\texttimes}10-3{\textendash}40{\texttimes}10-3), the ratio of kiln length to kiln diameter (L/D=1{\textendash}10), the kiln{\textquoteright}s inclination angle (β=0.1{\textendash}8o), the Froude number (Fr=10-3{\textendash}10-2), the rotational Reynolds number (Re=102{\textendash}16{\texttimes}103), and the P{\'e}clet number (Pe=5{\textendash}100). Data of 13,851 single case simulations are provided with this article. This includes the mean particle residence time, gas, bed and kiln wall temperatures, solid and gaseous species mass flows, heat fluxes, and the solid bed height over the kiln length. These comprehensive data have the potential to help in modeling, design, analysis, and optimization of rotary kilns used for the pyrolysis of biomass. The main characterization and interpretation is presented in the related main research paper by Pichler et\ al. (2021)[1].

Multi-phase reactive flows are an immanent aspect of chemical engineering applications, e.g. solid fuel conversion, thermo-chemical energy storage, or heterogeneous catalysis. In recent years, applying computational methods for process optimization or intensification has become more popular. Computational Fluid Dynamics (CFD) provides a spatially resolved, steady-state or transient method to investigate complex processes. Flow, temperature, species profiles, and homogeneous chemistry are readily available in common CFD codes. Contrary, heterogeneous chemistry is typically only available in the Eulerian-Lagrangian (EL) modeling approach, while Euler-Euler (EE) implementations of heterogeneous chemistry are hardly available. Despite ever-increasing computational resources, modeling large- or industry-scale aggregates in the EL framework by e.g. CFD-DEM is still prohibitive. As a consequence, EE two-phase or multi-phase models are often employed to reduce the computational effort of granular phases by modeling their rheology with the Kinetic Theory of Granular Flows (KTGF). Providing a generic framework to include heterogeneous chemistry in the EE framework seems crucial to improve the application of CFD in industry-scale process development, optimization, or intensification. In this work, we present our implementation of such a multi-phase chemistry framework in the open-source CFD toolbox OpenFOAM{\textregistered}. The novel framework integrates seamlessly into the stock OpenFOAM{\textregistered} multiphaseEulerFoam solver and provides heterogeneous chemistry models of different complexity. The currently implemented heterogeneous chemistry models focus on gas-solid reactivity and range from detailed chemistry based on the SurfaceCHEMKIN formalism to effective rate approximations. A thorough introduction and discussion of the generic EE multi-phase chemistry framework are followed by an overview of the currently available gas-solid chemistry models. In the last part, we highlight the capabilities of the novel framework by presenting selected reactive multi-phase processes.

In this work, we derive a model for the anisotropic effective thermal conductivity of bricks based on the unit cell model approach. The presented model considers conduction and surface-to-surface radiation in the brick. Four different radiation models are presented, compared, and validated using fully resolved computational fluid dynamics simulations for three different brick profiles and experiments. Good agreement with fully resolved computational fluid dynamics simulations with and without radiation is found. The validated model was then applied in a global sensitivity study and to simulate the temperature distribution in brick stacks in a tunnel kiln segment under firing conditions.

The Eddy Dissipation Concept (EDC) is a well working concept for turbulent reacting flows, which depicts the influence of chemical reactions as well as turbulence. The problem when using detailed chemical mechanisms - necessary for more information about radical species and pollutants - is the vastly increased computational demand. Operator splitting and in situ adaptive tabulation (ISAT) can be a way to reduce the computational effort and improve the application of detailed chemical mechanisms with the EDC. Two operator splitting mechanisms are presented and used for the simulation of Sandia Flame D. The computational time can be decreased and the results fit well to the experimental results.

The Eddy Dissipation Concept (EDC) is common in modeling turbulent combustion. Several model improvements have been proposed in literature; recent modifications aim to extend its validity to Moderate or Intense Low oxygen Dilution (MILD) conditions. In general, the EDC divides a fluid into a reacting and a non-reacting part. The reacting part is modeled as perfectly stirred reactor (PSR) or plug flow reactor (PFR). EDC theory suggests PSR treatment, while PFR treatment provides numerical advantages. Literature lacks a thorough evaluation of the consequences of employing the PFR fine structure treatment. Therefore, these consequences were evaluated by employing tests to isolate the effects of the EDC variations and fine structure treatment and by conducting a Sandia Flame D modeling study. Species concentration as well as EDC species consumption/production rates were evaluated. The isolated tests revealed an influence of the EDC improvements on the EDC rates, which is prominent at low shares of the reacting fluid. In contrast, PSR and PFR differences increase at large fine fraction shares. The modeling study revealed significant differences in the EDC rates of intermediate species. Summarizing, the PFR fine structure treatment might be chosen for schematic investigations, but for detailed investigations a careful evaluation is necessary.

In current literature two main approaches are used for the simulation of membrane contactors. One route considers membrane modules only in 1D for process simulation applications, the other route focuses on 3D simulation of modules using Computational Fluid Dynamics to provide very detailed information about membrane mass transfer or geometrical influences on the module performance. A new CFD algorithm is introduced in the current work. It is capable of performing both 3D and 1D simulations using the same code {\textendash} 1D to be used in fast process simulation applications whereas the 3D method can be applied for fully resolved CFD applications. Using experimental results from pure gas permeation of a hollow fiber module, it was demonstrated that 1D and 3D simulations compare with less than 2\% deviation on a global scale. Based on the 3D simulations, it was found that the arrangement of the fibers can lead to high velocity zones close to the module walls. It was demonstrated that the 1D CFD method performs well even for almost pure gases like CH4 at retentate side, by running simulations of a pilot scale biogas separation module in co- and counter-current configurations.

We present a novel micromachined fast diffusion based mixing unit for the study of rapid chemical reactions in solution with stopped-flow time resolved Fourier transform infrared spectroscopy (TR-FTIR). The presented approach is based on a chip for achieving lamination of two liquid sheets of 10 μm thickness and \~{}1 mm width on top of each other and operation in the stopped-flow mode. The microstructure is made on infrared transmitting calcium fluoride discs and built up with two epoxy negative photoresist layers and one silver layer in between. Due to the highly laminar flow conditions and the short residence time in the mixer there is hardly any mixing when the two liquid streamlines pass through the mixing unit, which allows one to record a mid-IR transmission spectrum of the analytes prior to reaction. When the flow is stopped, the reactant streams are arrested in the flow-cell and rapidly mixed by diffusion due to the reduced interstream distances and the reaction can be directly followed with hardly any dead time. On the basis of two model reactions{\textemdash}neutralisation of acetic acid with sodium hydroxide as well as saponification of methyl monochloroacetate{\textemdash}the performance of the mixing device was tested revealing proper functioning of the device with a time for complete mixing of less than 100 ms. The experimental results were supported by numerical simulations using computational fluid dynamics (CFD), which allowed a reliable, quantitative analysis of concentration, pressure and flow profiles in the course of the mixing process.

Schwerpunkt der Berechnungen waren das Verhalten der Str{\"o}mung im Diffusor (Abl{\"o}sungserscheinungen), die Simulation der partikelbeladenen Gasstr{\"o}mung und die Turbulenzmodellierung.

In dreidimensionalen, kreisrunden Diffusoren mit konstantem Verh{\"a}ltnis der Einlauf- und Auslaufquerschnitte wurden die Aufweitungswinkel variiert, um festzustellen, ab welchem keine Str{\"o}mungsabl{\"o}sung mehr auftritt. Als Kriterium f{\"u}r das Vorhandensein einer Grenzschichtabl{\"o}sung wurde das Auftreten einer R{\"u}ckstr{\"o}mung im Diffusorteil bewertet. Die Untersuchung wurde durch Simulation einer Gasstr{\"o}mung (ideales Gas) mit Hilfe des kommerziellen CFD-Programmes FLUENT durchgef{\"u}hrt.
