摘要
基于一维动态可压缩气体流动方程建立了装甲车辆发动机冷却系统空气流动的仿真模型 ,考虑了车辆动力舱内流道几何尺寸、壁面摩擦、散热器传热、风扇做功以及分支流动对冷却气流的影响。对一台履带式装甲车辆发动机冷却系统的空气流动进行了实例仿真计算 ,为研究装甲车辆发动机冷却系统空气流动的性能提供了一种理论分析手段。
A simulation model of the cooling airflow for armored vehicle engines has been developed,based on one dimensional transient compressible flow equations.The effects of flow passage geometry,wall friction,radiator transfer heat,fan work and branch flow on cooling airflow have been taken into account in the model.An exemplary simulation has been carried out for the cooling airflow of a tracked armored vehicle engine.This simulation model can be used as a theoretical analysis means for studying cooling airflow performance of armored vehicle engines.
