Motivation

Understand the fundamental modeling aspects related to multiphase turbulent flows with significant interphase coupling. More accurately account for particle size change due to various chemical and physical processes in industrial reactors.

Approach

Euler-Lagrange simulations, Quadrature-Based Moment Methods, Turbulence models for gas-particle flows[/vc_column_text][vc_row_inner][vc_column_inner el_class=”” width=”1/2″][vc_single_image image=”129″ border_color=”grey” img_link_large=”” img_link_target=”_self” img_size=”large”][/vc_column_inner][vc_column_inner el_class=”” width=”1/2″][vc_column_text css=”.vc_custom_1437502111229{background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}”]

Accomplishments

Novel multiphase turbulence model for gas-particle flows. Novel polydisperse gas-particle model based on QBMM solution to kinetic equation.

Significance & Impact

Demonstrated that for both homogeneous and wall-bounded, gas-particle flows a turbulence model must account for the anisotropy of granular energy in order to predict correct flow dynamics.
Facilitate the numerical simulation and scale up of energy systems such as gasifier.
