Project Description

This research effort will apply advanced computational techniques to develop reduced order models in the case of reacting multiphase flows, based on high fidelity numerical simulation of gas-solids flow structures in risers and vertical columns obtained by the Multiphase Flow with Interphase eXchange (MFiX) software. The project will also generate numerical data necessary for validation of the models for multiple fluidization regimes; expose minority students to scientific research in the field of fluid dynamics of gas-solids flow systems; and maintain and upgrade the educational, training, and research capabilities of Florida International University.

Project Benefits

The model developed is expected to speed up the scale-up process for the design of fluidization systems by providing accurate solutions that match the full-scale models. The computational work completed is expected to lead to the development of a methodology for obtaining reduced order models that is applicable to the system of gas-solid flows.
