开缝肋片表面的数值模拟及特性分析

Numerical simulation and characteristic analysis of slotted fin surfaces

在不同雷诺数、不同开缝辐射角度下,应用SIMPLE算法对空调用辐射型开缝肋片表面的传热及流动阻力特性进行了数值模拟,根据场协同原理分析了计算结果,得出了换热量随雷诺数和开缝角度的变化规律。

Simulates the characteristics of heat transfer and flowing resistance of heat exchanger surface with radial type slotted fin at different Reynolds number and radial angle with SIMPLE algorithm. Analyses the calculating results based on the theory of field synergy and obtains the varying regularity of heat exchange rate with Reynolds number and radial angle.
