摘要
本文根据流体力学和数值传热学的基本方程 ,建立了陈列柜风幕及柜内空气流动和换热的二维数学模型 ;并采用湍流模型和SIMPLER算法进行了数值计算。文中重点分析了风幕送风速度、环境空气温度和送回风口尺寸三个因素对风幕性能的影响。
In this paper,a two dimensional mathematical model of the air curtain is built based on several hypotheses.By using this model,a numerical computation is performed with turbulence model and SIMPLER algorithm.In the investigation,the inlet velocity of the air curtain,the temperature of environment and the width of the inlet and the outlet are taken into account.The conclusion of this paper will provide some guidances for the optimization design and experiments on display cases.
