| 摘 要： | 利用Fluent软件对一种全焊式双波纹板式换热器的板束传热与流动性能进行数值模拟，运用场协同原理进行强化传热机理分析的同时对双波纹板式换热器进行传热实验，验证数值模拟和理论分析的合理性。结果表明：双波纹结构使得流体在流道形成湍流，减薄板片的层流边界层并且改善了主流区域的速度与温度梯度的协同程度，强化传热。双波纹板束本身的传热系数受到板束热侧入口尺寸的影响，并且在固定尺寸上达到峰值，增大冷热流体入口速度可以提升板束的传热能力，同时也受到压降增大的影响。

| Abstract: | Using the software Fluent，numerical simulation was performed for heat transfer of double corrugated plates of heat exchanger developed for gas heat exchange. Numerical simulation was compared with the experimental results，and analyzed with the field synergy principle. Fluid flows turbulent because of double corrugates plates. The double corrugated plates thinned laminar boundary layer and improved synergy of the velocity and temperature field to enhance heat transfer. The efficiency of double corrugated plates was influenced by the size of entrance in hot side，and might reach a peak at a specific size. Increasing velocities of both cold and hot flows could enhance efficiency，but higher pressure drop might have a negative effect. |
