波节管强化传热的三维数值模拟分析研究OA北大核心CSTPCD
Three Dimensional Numerical Simulations on Enhanced Heat Transfer of Corrugated Tube
在入口雷诺数Re从5 000到25 000的变化范围内,分别采用5种不同尺寸的波节管,利用三维数值模拟方法以及场协同原理对波节管的管内流动及传热特性进行分析,发现波节管的传热效果明显优于等长度且内径等于波节管小径的光壁管,同时发现波节管传热能力随着波峰处的直径和相邻两波节之间的距离增大而增大,而波节的长度对传热影响较小.
The flow and heat transfer in five different sizes of corrugated tubes with Reynolds number from 5 000 to 25 000 at the inlet are analyzed by three dimensional numerical simulation and field synergy principle. The results show that the heat transfer performance of corrugated tube is better than that of straight tube with same length and inner diameter, the heat transfer capacity of corrugated tube will be improved with the increase of depth and pitch a…查看全部>>
