摘要

基于经验证了的二维冻干模型对瓶装物料的冷冻干燥过程进行了数值计算

利用计算结果对径向热质传递的影响进行了分析 .结果表明 :瓶侧面的径向传热影响显著

但忽略水蒸气在径向上的传递作用不会给模拟计算结果带来明显误差 .

Abstract

A comprehensive two-dimensional model for freeze-drying of materials in vials was presented and solved numerically by the authors

and was examined by experiments in previous works.By the use of the two-dimensional model

the numerical simulation of vial freeze-drying of skim milk is made in this paper.The effects of radial transfer of heat and mass on freeze-drying process of materials in vials are analyzed by using simulating results.The results show that the influence of side heat transfer on freeze-drying process is significant

but the effect of radial transfer of vapor can be ignored.
