摘要
为了提高可移动式救生舱生命保障系统设计的时效与经济性,采用数值模拟方法研究舱内制冷净化一体机的数量和布置对舱内气流组织特性与舒适性的影响。以某型16人舱为例,基于有限体积法软件FLUENT建立救生舱内部空间三维模型,模拟分析单制冷净化一体机与双制冷净化一体机对角布置方式下舱内的速度场与温度场,并在此基础上对舱内舒适性进行评价。模拟结果表明:为满足16人舱内部气流组织与舒适性要求需采用双制冷净化一体机对角布置的方式。研究结果为救生舱内部设备的选择与布置提供一定依据。
In order to improve the timeliness and economy of the design of life support system of movable refuge chamber,the numerical method is used to study the effect of the number and arrangement of the refrigeration-purity machine on flow characteristics and comfort of a certain type of refuge chamber.A 3-D simulation model is developed by FLUENT based on the finite volume method.The velocity field and temperature field under different conditions are studied.The comfort of the chamber is evaluated.The simulation results show that the double refrigeration-purity machine system can meet the requirements of the flow characteristics and the comfort.This work can provide some foundation for the model selection and arrangement of the facilities in the refuge chamber.
