A numerical method is utilized in this paper to study the effects of varying divider inclination angle on the flow structure and heat transfer characteristics in a ribbed two-pass channel for Reynolds number varying from 10,000 to 50,000. The studied divider inclination angles are $-3^{°}$,$-2^{°}$,$-1^{°}$,$0^{°}$, $+1^{°}$, $+2^{°}$ and $+3^{°}$. The ribs have an orientating angle of ${45}^{°}$. The results show that the heat transfer in the bend region and in the passage upstream the bend is enhanced significantly and the heat transfer in the passage downstream the bend is reduced compared to a channel with a straight divider wall as the divider wall inclination angle varies from $-3^{°}$ to $+3^{°}$. Channels with inclined divider wall produce higher pressure drop and friction factors than a channel with straight divider wall. According to the results, a channel with $-1^{°}$ inclined divider shows the best thermal performance among all the channels investigated. The flow structure and heat transfer characteristics for all the channels are depicted in detail and discussed in this study.

本文采用数值方法研究了变化的分流器倾角对雷诺数在10,000到50,000之间变化的带肋二通通道中流动结构和传热特性的影响。研究的分频器倾角为$-3^{°}$，$-{\mathrm{2个}}^{°}$，$-{\mathrm{1个}}^{°}$，$0^{°}$， $+{\mathrm{1个}}^{°}$， $+{\mathrm{2个}}^{°}$ 和 $+3^{°}$。肋的定向角为${45}^{°}$。结果表明，与分隔壁为笔直的通道相比，随着分隔壁倾角的变化，弯曲区域上游和折弯上游通道中的传热显着增强，折弯下游通道中的传热减少。$-3^{°}$ 至 $+3^{°}$。与具有直的分隔壁的通道相比，具有倾斜的分隔壁的通道产生更高的压降和摩擦系数。根据结果​​，$-{\mathrm{1个}}^{°}$倾斜的分隔器在所有研究的通道中显示出最佳的热性能。所有通道的流动结构和传热特性均已详细描述并在本研究中进行了讨论。
