装甲输送车乘员舱内三维空气流动与传热的数值计算

A NUMERICAL STUDY ON THE 3-D AIRFLOW & HEAT TRANSFER IN AN ARMORED PERSONNEL CARRIER PASSENGER COMPARTMENT

本文建立了装甲输送车乘员舱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二方程紊流模型、非结构化网格和有限容积法对某装甲输送车乘员舱内的空气流场与温度场进行了三维数值仿真计算与分析 。

A physical and mathematical model for the computation of 3 D airflow and heat transfer in an armored personnel carrier passenger compartment is set up. By a two equation k ε turbulence model and FVM(finite volume method)with unstructured grid,the 3 D distributions of airflow and temperature fields in an armored personnel carrier passenger compartment are numerically calculated. A theoretical basis for the study on the optimization of the armored personnel carrier passengers' survival environment was given.
