摘要
舱内速度场、温度场等气流特性的模拟分析是救生舱生命保障系统设计的重要内容。以某型矿用可移动式救生舱为例,采用有限体积法软件FLUENT,基于稳态不可压缩N-S方程与k-ε湍流模型,建立了救生舱内部空间三维模型,模拟分析了送风风速对舱内速度场、温度场和二氧化碳浓度场的影响。在此基础上,通过真人综合防护试验对救生舱内温度场与二氧化碳浓度场进行验证,试验结果与计算分析吻合良好。
The simulation of flow characteristics in refuge chamber is important for the research and de- sign of the life support system. Taking a certain type of refuge chamber for example, based on the steady state incompressible N-S function and k-e tturbulence model, a 3-D simulation model is developed by FLUENT using the finite volume method. The effects of different air velocity on velocity field, tem- perature field and carbon dioxide concentration field are studied. On this basis, a real comprehensive protection experiment is conducted to verify the simulation results, the simulation and experimental re- sults have good concordance.
