人体热舒适参数与舱室热环境双向耦合研究

Study on Bidirectional Coupling of Human Thermal Comfort Parameters and Cabin Thermal Environment

现有驾驶舱热系统偏向于研究热环境的气流组织参数,较少考虑甚至不考虑人体热调节的作用,使驾驶舱热系统的仿真结果在评估人体热舒适性时准确度不高。采用CFD(computationalfluid dynamics)方法,通过能量方程、RANS(reynolds-averagednavier-stokes)方程以及N-S(navier-stokes)方程的并行求解,将人体温度分布与舱室热环境参数相结合,建立基于人体热调节的舱室热系统模型。此模型考虑了人体热调节作用与热环境气流组织参数的相互影响,最终实现了人体热舒适参数与驾驶舱热环境的双向耦合。

At present,for the existing cockpit heat system,are studied more the airflow tissue parameters of the thermal environment and the human heat regulation is taken into account less,which leads to the low accuracy of simulation result evaluating the human thermal comfort.Through CFD(computational fluid dynamics)method,energy equation,RANS(reynolds-average navier-stokes)equation,and N-S(navier-stokes)equation,by combining the human temperature distribution with the cabin thermal environment parameters,the cabin heat system model based on the human heat regulation is established.The model considers the interacting influence of the human thermal regulation and the thermal environmental airflow tissue parameters,and finally realizes the bidirectional coupling between human thermal comfort parameters and the cockpit thermal environment.
