Project Description

The overall goal of this project is to improve the performance and accuracy of the Multiphase Flow with Interphase eXchanges (MFiX) code frequently used in multiphase flow simulations. The specific objective of the project is to use a novel and validated Direct Numerical Simulation particulate flow program combined with the Immersed Boundary method (DNS-IB) to establish, modify, and validate needed constitutive equations for the heat and mass transfer from non-spherical particles and clusters of particles to be used in the MFiX code.

Project Benefits

This project will focus on deriving, validating, and supplying constitutive equations for the MFiX code. The equations developed will be ready to be used in the MFiX code and will significantly improve its predictive capabilities. With more realistic simulation capability, more efficient and less costly advanced fossil energy-based power generation systems can be designed and built.
