| 摘 要： | 我国冷库的建设数量近年来增长迅速,可多数冷库中的气流分布并不合理,而风机的布置形式是影响冷库中气流分布的一个重要因素。运用SIMPLE算法,结合波兴涅克（Boussineq）假设,对目标冷库中不同的冷风机安装形式进行三维数值模拟。模拟结果显示目标冷库中采用两个三出风口的风机吹风比采用三个两出风口的风机吹风所引起的气流场均匀性更好;同时针对后者造成的射流偏移,对风机位置进行改变后得出了冷库中的流场较改变前均匀性提高。数值模拟的结果对中型冷库和大型冷库中风机的安装形式和安装位置提供了参考依据。

| Abstract: | In recent years,the number of cold stores in domestic has increased rapidly,but the air distributions in most cold stores are not reasonable and the arrangement of the fans is an important factor of effecting the air distribution.SIMPLE revised was used and Boussineq assumption was combined,three dimensional numerical simulations were done on different kinds of cold fan arrangement in target cold store.The result of simulations showed that the uniformity of the air distributions in those had three air outle... |
