NUMERICAL-SIMULATION OF GAS-PARTICULATE FLOW-THROUGH CURVILINEAR POROUS CHANNELS

The problem of gas-particulate flow through a two-dimensional porous c hannel bounded by curved boundaries is considered. The boundary functi on transformation is employed as a method of transforming a curvilinea r physical domain onto a regular computational domain. Solution to the transformed governing equations is obtained in the computational doma in via the finite difference procedure. Results obtained illustrate th e effect of the flow parameters (Reynolds number, permeability and dus t parameters) on the flow regimes. These results represent the first a ttempt at validating the dusty gas flow model employed in the study. ( C) 1998 Elsevier Science Inc. AU.rights reserved.
