食品冷却抽真空过程流场影响参数分析(Parameters Analysis on Flow Performance in Food Vacuumizing Process)
真空泵 传热传质 流场 数值模拟
2010/12/28
建立了描述食品冷却抽真空过程的传热、传质模型,采用计算流体力学进行了非稳态模拟,实验表明模型与实际吻合较好。在此基础上,对影响流场的参数:真空泵抽速、容器自由容积、是否放置隔板进行了模拟研究。研究表明:真空泵抽速越大,真空室内的极限压力越小,真空室的最低温度越低,达到最低温度所消耗的时间越长;自由容积不影响真空室的极限压力,自由容积越大,真空室的最低温度越高,达到最低温度所消耗的时间越短;放置隔板...
