Abstract

Porous media combustion is one of the most efficient and has a wide-ranging application. Despite this, more investigation needs to be done in order to improve its efficiency and pollutant emission. In this research, the commercial simulation software is used to model and couple together the significant phenomena such as combustion, heat transfer, and fluid flow in porous media, which occur in this type of system. The free and porous media flow module was used to estimate fluid flow inside both fluid and porous media. Species formation and heat release during combustion were modeled by the transport of concentrated species module. Local thermal equilibrium was assumed for the energy equation and calculated by heat transfer in porous media module. Each physic was coupled together by two mechanisms—first, reaction flow, which coupled together between free and porous media flow and transport of concentrated species. Finally, nonisothermal flow coupled free and porous media flow with heat transfer in porous media. The combustion chamber, which is entirely filled with aluminum oxide pellets, is created for two dimensional axisymmetric. Physics-controlled mesh with finer element size is applied to generate mesh by the software to meet the specified need for each physic. Combustion behavior, velocity and temperature profile, and species formation are achieved from this simulation study.
