摘要
传统CFD算法在解决风幕流动与换热问题上存在缺陷。在射流基本理论的基础上,建立了自由单层冷风幕的流动与换热模型,并采用Абрамович积分方法求出了冷风幕的流速和温度分布。相对于传统CFD算法,仿真算法与实验测试结果更为吻合,计算也更为快速。
The CFD algorithm has some disadvantages when it solves the flow & heat transfer equations of air curtain.Based on the jet theory,the flow and heat transfer model of free & single cold air curtain were set up and A???????? integrated method was used to solve the velocity and temperature distribution of air curtain.The computational results show that the simulation algorithm is in more agreement with the experimental results than CFD algorithm and the simulation algorithm runs faster.
