The Brinkman-Lapwood-Forchheimer-extended Darcy model, with variable porosity, is used in the compressible momentum equations. For the energy equation, the local thermal equilibrium assumption is used between the fluid and the solid phases. Numerical solutions are obtained during the compression stroke. Flow and temperature fields are examined over ranges of the principal parameters, i.e., the Reynolds number, the Darcy number, the porous medium length, the heat capacity ratio, and the thermal conductivity ratio. %8 2008-04-21
