Simulation of Uniform Fluidization in 2D Fluidized Bed
In this tutorial, we provide guidelines for modeling and simulation of uniform fluidization process. Predicting pressure drop in a uniformly fluidized bed has been the subject of intense study in the process industry. Using Eulerian models, we are able to study dense phase particulate flow and complex inter-phase momentum transfer in ANSYS Fluent.
Mathematical models and drag laws used for prediction of minimum fluidization conditions are semi-empirical in nature. Therefore, it is very important to use a drag law that predicts the beginning of fluidization where there is a balance between interfacial drag and body forces.
In this tutorial, we will investigate the hydrodynamics and bubble formation in a fluidized bed. In addition, we will show how to modify a drag law for granular gas-solid flow.
You will also learn how to do the following through this tutorial:
- How to customize a drag law for granular gas-solid flow
- Predicting the pressure drop in an uniformly fluidized bed using the Eulerian models
- Solving the uniform fluidization problem
- Also, post-processing and analyzing the resulting data
Problem Description for Uniform Fluidization Modeling
In order to model Uniform Fluidization, we use the Syamlal-O’Brien drag law. This drag law is widely used for various problems. But, we need to customize it for Uniform Fluidization Modeling by calculating the appropriate constants. Here we model 1m x 0.15m fluidized bed. The bed is close to packing with granular solids at 0.55 volume fraction. The inlet air comes in at 0.25 m/s and the top is modeled as an outflow.
