摘要
以计算流体力学和传热学为基础,建立了装有新风换气机房间三种气流组织形式的物理及数学模型.运用k-ε模型和SIMPLEC算法对装有新风换气机房间的流场及温度场进行了数值模拟,给出了温度场及流场的数值结果,分析了三种不同气流组织形式对室内流场及温度场的影响.
Based on computational fluid dynatnics and heat transfer theory, the paper builds the physics and mathematics model of three air flow forms in the room equipped with outdoor air exchange device. The paper uses k-ε model and SIMPLEC algorithm to simulate the flow field and temperature field of the room, the numerical results of temperature field and flow field are attained, and the effects of three air flow forms on indoor flow field and temperature field are analyzed.
