The main research content and result are as follows: 1 The two-dimensional governing equations for steady-stateflow and transient flow are derived based on unsaturated soil mechanics.
A two-dimension model for the flow field in catalytic converter was established, and the steadystateflow was simulated with the computational fluid dynamics (CFD) code.
