利用有限元程序研究了窗表面到相邻百叶窗的对流换热率。在这项研究中，窗户表面被模拟为一个等温的垂直平板，忽略了窗户和百叶窗之间辐射交换的影响。本研究旨在研究叶片间距d和叶片角度T对流型和对流换热系数的影响。给出了d=15、20、25、30和40mm值的结果，在每个间距处，叶片角度都是不同的，即q=0°、45°、-45°、80°。为了支持模型开发，研究了一种常见基本情况的建模，即等温垂直平板上的层流自然对流。对于d=15mm的局部热流和流量分布，也与实验结果进行了比较。 结果表明，百叶窗的存在对垂直平面的对流换热有影响。这些结果代表了分析百叶窗对开窗传热影响的第一步。未来的研究将研究太阳能在封闭表面的吸收以及对流/辐射耦合传热的影响。单位:SICitation:研讨会，ASHRAE交易，第105卷，第页。1999年2月2日，西雅图

The convective heat-transfer rate from a window surface to an adjacent venetian blind has been studied using a finite-element code. For this study, the window surface was modeled as an isothermal vertical flat plate, and the effects of radiation exchange between the window and blind were ignored. This investigation was undertaken to investigate the effects of blade-to-plate spacing d and blade angle T on the flow pattern and convective heat-transfer coefficients. Results are presented for values of d=15, 20, 25, 30, and 40 mm, and at each of these spacings, the blade angle was varied, i.e.,q=0°, 45°, -45°, 80°. To support model development, the modeling of a common base case, i.e., the laminar natural convection on an isothermal, vertical flat plate, was studied. Comparisons with experimental results were also made for both local heat flux and flow distribution for d =15 mm. The results of this paper indicate that convective heat transfer from a vertical flat surface is influenced by the presence of a venetian blind. These results represent a first step in the analysis of the effects of venetian blinds on fenestration heat transfer. Future studies will investigate the effects of solar energy absorption in the blind surface and coupled convective/radiative heat transfer.Units: SI
