Abstract
The transfer phenomenon in catalytic converter was numerically investigated by taking into account the influence of heat effects and aerodynamics. The problem is solved using 3-D model in entire region of laminar flow of viscous gas. The influence of near-wall non-uniformity of porosity on formation of aerodynamics, temperature and concentration pictures of process was studied. The possibility of existence of different regimes of heterogeneous catalytic reactions across reactor depending on gasdynamic and thermophysical parameters is shown.
