膨胀干燥机橡胶熔体流动数值模拟分析

摘要

膨胀干燥机是橡胶后处理的重要设备,通过膨胀干燥机可脱去橡胶熔体中 90％的水分.基于FLUENT软件,对橡胶熔体在膨胀干燥机流道中的流动进行数值分析,并根据速度分布云图及压力分布云图,分析橡胶熔体在流道中的流动规律.研究结果可为进一步研究工艺参数对橡胶质量的影响奠定基础.%The expansion dryer was the critical equipment for the finishing unit of rubber plant.It could take off 90％moisture in the rubber melt.The flow behavior of rubber melts in the channel of the expansion dryer was analyzed by FLUENT.Observing the nephogram of the distribution of rubber melts speeds and stress nephogram,the flow rule of rubber melts in the expansion dryer was analyzed.The following research directions were indicated.
