Project Description

This project will develop and validate new drag force correlations for the case of particle clustering, based on direct numerical simulation of gas-solids flow structures in risers and vertical columns; and validation of the proposed drag law by using the Multiphase Flow with Interphase eXchanges (MFIX) multiphase flow simulation code to compare the experimental data generated in this project with computational results generated by MFIX simulations.

Project Benefits

This project will focus on the development of an accurate drag correlation for gas-solid multiphase flow that includes the effect of clustered particles. These developments will allow scientists and engineers to more realistically simulate the hydrodynamics, gasification kinetics, and thermal behavior of complex gas-particle flow systems; enabling more efficient and less costly advanced fossil energy based power generation systems to be designed and built.
