摘要
为减小载人航天器热控、环控生保系统中并联热网络系统的质量 ,在一定的简化和假设的基础上 ,建立热网络流动与换热的物理和数学模型。以系统总换热面积最小为优化目标函数 ,用极值有理法求解 ,得到最佳冷媒流量分配率随各热组件效能的变化关系。热组件效能大 ,其冷媒流量分配率就大 ,效能小 ,则其流量分配率就小 ,且热组件的效能总小于其流量分配率。
Simplified mathematical models for the flow and heat transfer were used to reduce the system mass of the thermal control and environmental control and the life support system of manned spacecraft. The overall heat exchange area was used as the object function to optimize the flow rate distribution and the efficiency. A distributed flow was found to increase with the effectiveness and to be more than the effectiveness. The results provide a theoretical basis for the optimal design of the thermal network of manned spacecraft.
