摘要：建立基于化学反应的催化转化器的数值模型,并利用计算流体力学的方法,对催化转化器起燃过程内部压力场进行模拟。模拟结果显示,起燃过程中催化器内部压力不断升高,同时催化器入口和出口间的总压差也不断提高,压力损失也随之提高。

Abstract: The numerical modal of catalyst
converter was established based on the chemical reaction and the unsteady
pressure field can be solved by computational fluid dynamics method.The
simulation results show that pressure and the difference of total pressure
between inlet and outlet increase during the heating up, so the pressure losses
arise with the development of inlet pressure.
