数值模拟了二维方腔两顶角狭缝集中斜进风、两底角狭缝集中出风通风方式下的流动与换热。研究表明 :即使是具有对称结构的开口系统 ,其稳定的流型也可能是不对称的 ;斜进风通风方式在进风角度小于一定值时流动存在静态分叉 ,即随计算初场的不同会得到不同的解 ;这种不对称的流动仍具有较好的流场、温度场分布均匀性以及较高的换热能力 ;在工程上对斜进风进行研究时 ,必须用全场分析的方法 ;数值计算结果与可视化实验的结果得到了较好吻合。该研究为空间站舱内的通风换热系统的设计与选择及其工程应用提供一定的依据 Numerical simulation of two-dimensional square two-corner slit focused oblique into the wind, the bottom corner of the slit concentrated air flow ventilation and heat transfer mode. The results show that the stable flow pattern may be asymmetric even for an open system with a symmetrical structure. When the inlet wind angle is less than a certain value, Will get different solutions; this asymmetric flow still has better flow field, temperature field distribution uniformity and higher heat transfer capacity; engineering on the ramp into the wind, we must use the full analysis The numerical results are in good agreement with the experimental results. This study provides a basis for the design and selection of ventilation and heat exchange system in space station and its engineering application
