Abstract This study experimentally investigates the mixed-convection heat transfer on a moving vertical flat plate. The setup comprises a hanger–pulley system above a transparent volume in which the experimental model moves; a flywheel-motor assembly, which generates the oscillation movement; a power supply; and a datalogger. The experimental model comprises two copper plates on which the thermocouples are placed and Kapton heaters between the plates. For the study, heat flux was applied to the plate surface (q”) and the Womersley number (Wo) and dimensionless oscillation amplitude (Ao) were varied; the effects of these parameters on mixed-convection heat transfer were analyzed. The experiments were performed for four different values of Ao and five different oscillation frequencies with three different heat fluxes. The results show that heat-transfer performance is significantly affected by Ao, Wo, and heat flux applied to the plate surface. We observed that heat-transfer performance increases with the increase of both the Wo number and the dimensionless oscillation amplitude for all heat fluxes tested. The obtained results are presented as a function of dimensionless numbers. We also compare experimental results with other researchers' prior-published studies.

振动垂直平板上混合对流的实验研究

摘要 本研究通过实验研究了移动垂直平板上的混合对流传热。该装置包括一个悬挂在透明体积上方的滑轮系统，实验模型在其中移动；飞轮电机组件，产生振荡运动；一个电源；和数据记录器。实验模型包括热电偶放置在其上的两块铜板和板之间的 Kapton 加热器。在研究中，热通量被施加到板表面 (q") 并且沃默斯利数 (Wo) 和无量纲振荡幅度 (Ao) 发生变化；分析了这些参数对混合对流换热的影响。实验是针对四种不同的 Ao 值和五种不同的振荡频率以及三种不同的热通量进行的。结果表明，传热性能显着受 Ao、Wo 和施加到板表面的热通量的影响。我们观察到，对于所有测试的热通量，传热性能随着 Wo 数和无量纲振荡幅度的增加而增加。获得的结果表示为无量纲数的函数。我们还将实验结果与其他研究人员先前发表的研究进行比较。
