摘要
对工程实际中广为应用的紊流混合对流换热进行了数值研究,具有计算对象为具有对称边界条件的多进出口空调房间的传热.针对此对象编制了一个应用程序,并运用此程序在较宽的参数范围内对不同的配风方式及边界条件进行了数值模拟,得到了相应的速度场、温度场及其它物理量场的分析,进而总结出紊流混合对流换热的一些规律.通过与相关文献的对比,说明了本文数值模拟的有效性.
A numerical investigation for the turbulent mixed convection heat transfer which has been widely applied in engineering today is presented in this paper.The heat transfer in an air conditioned room with multiple inlets and outlets is studied.A practical program is worked out to simulate the flow field for different boundary conditions at a large range of parameters.The velocity field,temperature field and other fields are obtained.And some regularity can be summarized. By comparison with relevant articles,the validity of this numeral study is confirmed .
