| 摘 要： | 应用重整化群κ-ε紊流模型,分别计算并比较了非空态与空态空调列车室内空气三维紊流流场与温度场的分布特性。采用Monte Carlo法分析计算了太阳透射辐射和壁面间的辐射在车室内各固体壁面引起的附加热流变化,并以此作为能量方程的附加源项;对旅客产生的热负荷分别采用平用分布与空间分布处理方式,对比分析了采用不同热负荷分布方式对空调列车客室内三维空气流场与温度场分布的影响。研究分析表明:不同的热源处理方式对客室内流场与温度场由较大的影响。最后,应用试验研究的方法验证了采用数值模拟手段研究非空态空调列车室内气流组织的可靠性,为空调列车室内舒适环境的优化研究提供了依据。

| Abstract: | Distribution characters of 3-D velocity and temperature field in air conditioning railway passenger compartment(ACRPC) with passengers and no passenger were calculated and analyzed using RNG turbulence model.The effects of solar radiation and the solid face radiation were calculated by means of the Monte Carlo method and this auxiliary heat flow on the face of indoor solids was taken into account in the source term of the energy equation.The impact of different distributions of heat loads generated by passe... |
