摘　　要：应用计算流体力学和计算传热学方法对某车载雷达工作室内的三维空气流动和传热进行了模拟与数值计算。建立了车载雷达工作室内三维空气流动与传热计算的物理模型和数学模型,应用k-ε紊流方程模型、非结构化网格和有限容积法对某车载雷达工作室内的空气流场与温度场进行了三维数值仿真计算与分析,为该车载雷达工作室生存环境的改善与优化提供了理论依据和技术指导。Simulation and numerical computation of three-dimensional air flow and heat transfer in car radar chamber were carried out using computational fluid dynamics and heat transfer method. Three-dimensional physical model and mathematical model for air flow and heat transfer calculation was established. Three-dimensional simulation and numerical computation of air flow field and temperature field in certain car radar chamber was carried out using the turbulence model equations, unstructured grids and finite volume method. The purpose was to provide theoretical basis and technical guidance to improve the living environment of automotive radar.
