Numerical simulation of gas-particulate flow through curvilinear porous channels

摘要

The problem of gas-particulate flow through a two-dimensional porous channel bounded by curved boundaries is considered. The boundary function transformation is employed as a method of transforming a curvilinear physical domain onto a regular computational domain. Solution to the transformed governing equations is obtained in the computational domain via the finite difference procedure. Results obtained illustrate the effect of the flow parameters (Reynolds number, permeability and dust parameters) on the flow regimes. These results represent the first attempt at validating the dusty gas flow model employed in the study.
