摘要
本文将用于纯粹Stefan问题中的数位方法—定空间网格、交时间步长的方法推广应用到带有移动边界的干燥过程的传热传质耦合问题中,对干燥过程的三个干燥阶段的温湿度场进行了联合求解。分析了内外部因素对干燥过程的影响,为研究不同干燥条件下的各种具体多孔体的干燥过程提供了基础。
The numerical method that is used in pure stefan problems is extended to use in theheat and mass transfer coupled problem that contains a moving boundary,In this paperit is to solve the temperature and moisture fields in three periods of drying.The internal and external factors that have some influence on the drying process are analyzed,whichprovides a foundation of research on various drying process in different drying conditions.
