【摘要】 能量在间冷式空气循环系统中的流动规律对产品的能耗与性能具有重要的影响。为此,首先针对空气循环系统流固耦合的特征,提出了体积元法和局部划分法相结合的模块划分方法;在此基础上,利用CFD方法仿真计算得到相应的接口参数;然后,运用数值计算得出系统中各部分间的能量流动特性。最后以某型号间冷式冰箱空气循环系统为例,得出了其能量流动特性并验证了这里方法的有效性。更多还原

【Abstract】 The energy flow routine in each part of air circulation system plays a key role in affecting energy consumption and the performance of indirect-cool refrigerator. Therefore,the modeling approach,both the volume element method and local division method,is proposed. On this basis,CFD method was employed to calculate the interface parameters of the system.Then,the numerical calculation method was applied to exhibit energy flow characteristics among each part of the system.Finally,an instance of a certain type of indirect-cool refrigerator air circulation system is given to draw a description to the energy flow characteristics,which is synchronously a solid proof to the validation of method in this research.更多还原
