| 摘 要： | 通过三维CFD数值模拟软件ANSYS-CFX模拟分析一种新型波纹板式换热器——复合人字形板式换热器,分析其倾斜角β为20°～70°的传热和阻力特性,并对不同倾斜角的复合人字形板片进行场协同理论分析。数值计算结果表明:在β=60°时复合人字形板式换热器比普通人字形板式换热器的摩擦阻力系数低8%左右,综合性能提高25%左右;β=20°时速度场、温度场和压力场协同最好。

| Abstract: | A new type of corrugated plate heat exchanger(PHE)-double chevron plate heat exchanger was simulated by using three-dimensional CFD software—ANSYS-CFX.The heat transfer and resistance characteristics of the heat exchanger with the inclined angle of 20°-70° were analyzed.The field synergy analysis was done for the double chevron plate with different inclined angle.The results show that the flow resistance coefficient of the working fluid in double chevron-type PHE decreases by about 8%,and the comprehensive performance increases by about 25% compared with the ordinary chevron-type one.The velocity field,temperature field and pressure field are the best synergy of double chevron-type PHE with the inclined angle of 20°. |
