Fluidized Bed Bio-Reactor | ANSYS Fluent Training
This project investigates the fluidized bed bio-reactor. A fluidized bed bioreactor (FBR) is a type of device that can perform a variety of multiphase chemical reactions. In these types of reactors, a fluid (gas or liquid) is passed through a solid granular material (usually a catalyst) at a rate sufficient to suspend the solid and cause it to behave like a fluid.
This process, known as fluidization, gives FBR many important advantages. As a result, FBRs are used for many industrial applications such as the biomedical and food industries
The Eulerian multiphase model was used in this project to simulate the fluidized bed bioreactor. The granular sub-model was activated and the phase property model was used to obtain the granular temperature. Drag and virtual mass forces were also enabled between the phase pair of air and silicon (sand) while setting the value of restitution coefficient between the silicon particles equal to 0.9.
Also, the Ranz-Marshall model is used to calculate the heat transfer between the air and silicon particles which can calculate the new temperature of each phase after their interactions..
