Project Description

This project will develop a new fundamental drag model for solid-gas flows using the direct numerical simulation (DNS) method. The new model will consider the effects of particle rotation on the hydrodynamics of gas-solid flows.

Project Benefits

This project will focus on using the DNS method to obtain drag force and lift force exerted on solid particles suspended in gas phases and develop a new drag formula and a new lift force formula for solid particles. The database developed from this study will help to fill a data gap and formulate the constitutive equations necessary for more accurate Eulerian-Lagrangian multiphase flow models. Ultimately, this will contribute to the design of more efficient and environmentally benign power generation systems.
