摘要: 基于有限容积法建立波纹翅片管换热器流体流动与传热的计算模型,在不同送风速度工况下,分别
对6种不同波纹倾角结构换热器内流体的流动及传热进行了数值模拟,分析了流道内的温度场、压力场及速度场的
变化规律,得到了换热量、压降以及出口温度随入口风速变化的规律。结果表明,换热量、压降以及出口温度均随波
纹倾角的增加而增大;换热量随着送风速度的加快而增加,压降及出口温度随着送风速度的加快而降低;翅片板间
流体的流动与传热存在比较明显的不均性,导致换热管背风侧存在明显的传热“死区暠。

Abstract: Based on finite volume method, a threedimensional calculation model of a wavy fin exchanger was built up for fluidflow and heattransfer study, and using CFD software, numerical simulation were carried out for fluid flow and heat transfer inside the heat exchanger of 6 different inclination angles under conditions of different air velocities. The variations of the temperature field, pressure field and velocity field in the channels were analyzed, and the variations of heat transfer, pressure drop and outlet temperature with the inlet velocity were obtained. The results show that the heat transfer, pressure drop and outlet temperature increases with the increase of the corrugation inclination; the heat transfer increases while the pressure drop and outlet temperature decreases with the rising flow velocity;obvious nonuniformity of flow and heat transfer exists between the fins,resulting in obvious heat transfer "dead zone" at the leeward side of the heat transfer tube.
