Development of a detailed cold flow model of a multi‑phase reactor

Objectives:

• Literature survey and documentation of suitable scaling laws
• Development of a scaling method for multi‑phase processes
• Scaling of a large‑scale industrial process to lab‑scale

Results:

• Scaling method for industrial multi‑phase processes
• Lab‑scale cold flow model of a selected large‑scale industrial process

Description:

CFD simulations can help to understand industrial processes better or to design processes. However, model validation using lab‑scale experiments is required to ensure physically correct results of the simulations. The lab‑scale experiments need to be scaled according to certain scaling laws, which ensure similarity, of e.g. Reynolds and Froud number, between model and original process.

The main aim of this work is the evaluation of the scaling behavior of industrial multi‑phase reactors. The first part includes a thorough literature survey on available scaling approaches and their documentation. A scaling method for multi‑phase reactors should then be defined based on the findings of the literature survey. The new scaling method should enable the scaling of (reactive) 3‑phase processes to lab‑scale. Following this, the new method should be applied to design a lab‑scale cold flow model of a selected large‑scale industrial process.
