摘要
采用数值模拟的方法考察了车用催化器的非稳态性能。模拟结果正确地反映了冷启动过程中催化器载体温度场的变化规律,并且表明了气体浓度场的变化规律。
The unsteady performances of automotive catalytic converter were investigated by numerical simulation.Simulation results reflected the transformation characteristics of temperature fields of catalytic converter monolith correctly,and indicated the transformation characteristics of gas concentration fields.
