Abstract Heat and flow characteristics of V-shaped protrusion/concavity combination with miniature V-rib has been investigated numerically at flow Reynolds number of 50,000. With suitable baseline studies, a total of six different configurations viz. (a) V-rib only, (b) ‘V-rib and V-protrusion’, (c) ‘V-rib and V-concavity’, (d) V-protrusion only, (e) V-concavity only, (f) Sparse V-rib, were studied in a square channel with the above features installed on single wall. With air as the working fluid, the heat transfer mechanism and pressure drop characteristics were compared for all the configurations. The compound configuration of ‘V-rib and V-protrusion’ exhibited the highest thermal hydraulic performance (THP) of 2.15.

V型凸/凹结合微型V型肋的热流特性

摘要 在流动雷诺数为50,000 时,数值研究了V 形凸凹组合与微型V 肋的热流特性。通过合适的基线研究,总共有六种不同的配置,即。(a) 仅 V 型肋,(b) 'V 型肋和 V 型突起',(c) 'V 型肋和 V 型凹面',(d) 仅 V 型突起,(e) 仅 V 型凹面, (f) 稀疏 V 形肋,在方形通道中进行研究,上述特征安装在单壁上。以空气作为工作流体,比较了所有配置的传热机制和压降特性。“V 形肋和 V 形突起”的复合配置表现出最高的热水力性能 (THP),为 2.15。
