CFD Analysis of Two-Phase Flow in a Packed Bed Reactor

Project Description

1.  Develop gas-liquid counter current flow follow a single spheres surface (finished)
2. Apply multi-spheres in a normal packing in the cylinder having the same diameter as the experiments, and then cut a small concentric cylinder including some whole spheres and half spheres to run gas-liquid counter flow. Determine the pressure drops.(finished)
3. Do the gas-liquid counter flow experiments to measure the pressure drops, and compare the results between simulation and experiments.
4. Use porous media model in the CFD simulation to determine the void fraction in which the results from CFD simulation are agreed to the experiments.

Students

Yang, Li - Graduate Student

Software

All three students will use Ansys14.0-fluent to simulate the water and air flow in a fluid domain and test the pressure drop as results.

Project Description

1. Develop one-D, two-D and three-D models that can simulate process of generating a single liquid droplet in airflow stream with variable velocity.
2. Compare these simulation results with simple experimental results which will be conducted by other students.
3. Develop a prototype design using these models.
4. Further seek a new mechanism to control droplet generation and size distribution using these computational methods.
