Simulated Computation of Combined Ventilation and Temperature Field of Marine Brushless Non-salient Pole Generator

该文针对船用隐极发电机混合通风风路的结构 ,建立多元二次非线性回路压降方程组 ,引入函数风阻使之降幂成为多元一次非线性方程组 ,以解算出各等效风路的空气流量 ;引入气体热流 ,构造非线性节点热流方程组 ,以解算出求解域中各节点的温度。

In this paper ,multiple non-linear quadratic coupled equations are established for pressure drop of air passage of combined ventilation configuration of marine non-salient pole generator .And then ,by using a concept of functional air drag ,the equations are depowered to multiple linear coupled equations so as to solve air flow rate of equivalent air passage ;by using a concept of heat flux of air , non-linear coupled equations for heat flux of pitch points are established so as to solve temperature value at pitch points in the solved domain .
