This numerical study investigated a single air jet impingement at a constant temperature. Different RANS turbulence models, namely the v²-f model and four Reynolds stress turbulence models (the linear pressure-strain model, the quadratic pressure-strain model, the stress-omega model and the stress-BSL model) were employed to simulate and compare the numerical results with other published measurement data. Here, we show that the v²-f model has better numerical precision in simulating the local Nusselt number and velocity profiles and is in good agreement with a variety of Reynold numbers. These findings can assist scientists or engineers to improve mathematical turbulence modeling and industrial equipment for further development and to enable innovation.

该数值研究调查了在恒定温度下的单个空气射流冲击。采用不同的 RANS 湍流模型，即v ² - f模型和四种雷诺应力湍流模型（线性压力-应变模型、二次压力-应变模型、应力-ω 模型和应力-BSL 模型）来模拟和将数值结果与其他已发布的测量数据进行比较。在这里，我们证明v ² - f模型在模拟局部努塞尔数和速度剖面时具有较好的数值精度，与多种雷诺数吻合较好。这些发现可以帮助科学家或工程师改进数学湍流建模和工业设备，以进一步开发和实现创新。
