摘要
应用CFD技术,采用大型的计算流体力学软件Fluent软件建立催化转化器数学模型,并对其起燃过程进行了数值模拟研究。结果表明:催化转化器起燃过程的数值模拟基本上反映了催化转化器起燃过程的实际情况,所得到的速度场、温度场、浓度场和压力分布趋势正确合理。
Mathematical model for catalytic converter was constructed to simulate its light-off course with CFD technology based on fluent software platform. The results show that numerical simulation results of light-off course for catalytic converter reflect fact basically and the distributing trends of velocity field, temperature field and stress are precise.
