本文提出了一种优化设计方通道的方法，该通道在两侧壁面上挤压出V形方肋，以增强湍流换热。基于响应面的优化是一种优化技术，采用雷诺平均Navier-Stokes分析。剪切应力输运（SST）模型被用作湍流闭合。在几种不同雷诺数下，平均换热系数的计算结果与实验数据吻合较好。肋间距与肋高度比、肋高度与通道高度比以及肋的攻角被选为设计变量。目标函数定义为传热和摩擦损失相关项与加权因子的线性组合。采用D-最优方法确定训练点，作为实验设计的一种手段。在一定的加权因子范围内，得到了设计变量的最优值。
This work presents an optimization procedure for design of a square channel with V-shaped square ribs extruded on both walls to enhance turbulent heat transfer. The response surface-based optimization is used as an optimization technique with Reynolds-averaged Navier-Stokes analysis. The shear stress transport (SST) model is used as a turbulence closure. Computational results for average heat transfer coefficient show good agreement with experimental data at several different Reynolds numbers. Rib pitch-to-rib height ratio, rib height-to-channel height ratio, and the attack angle of the rib are chosen as design variables. The objective function is defined as a linear combination of heat transfer and friction loss-related terms with a weighting factor. D-optimal method is used to determine the training points as a mean of design of experiment. Optimal values of the design variables have been obtained in a range of the weighting factor.
