摘　　要：针对静音型电源车车舱内空气流动及传热的特点,建立了车舱内部计算流体力学(Computational Fluid Dynamics,CFD)仿真模型。采用稳态不可压紊流模型和标准kε模型,对车舱内柴油发电机组及两级消声器的温度分布情况进行了仿真计算,并利用环境模拟试验对仿真计算结果进行了验证,计算值与实测值比较吻合。计算与试验结果表明,当环境温度不高于45℃时,电源车车舱通风散热结构能满足发电机组和消声器的散热要求。Based on air-flow and heat transfer characteristics of the quiet power vehicle compartment, CFD simulation model of the compartment is established. By using steady incompressible turbulence model and standard k-ε model, temperature distribution of diesel generator and two mufflers in the compartment is calculated and verified through environmental simulation test and the calculation results are consistent with the measured values. The results show that ventilation and heat dissipation of the power vehicle can meet the requirements of heat dissipation of generator set and mufflers.
