论文摘要
我们演示了基于代数结构的模型(ASBM)与单方面Spalart-Allmaras(SA)模型之间的耦合,该模型提供了一个简单的途径,可以在工程湍流封闭中带来结构信息。测试了混合模型的估计能力,该流量通过具有无流量控制和稳定吸力的驼峰模型的流量进行了测试。 ASBM-SA模型对流向雷诺的应力分量产生了令人满意的预测,而与实验的定性一致性是针对横向分量实现的。关于剪切应力分量,与整个域中的SA相比,ASBM-SA闭合提供了改进的预测。
We demonstrate the coupling between the Algebraic Structure-Based Model (ASBM) and the one-equation Spalart-Allmaras (SA) model, which provides an easy route to bringing structure information in engineering turbulence closures. The estimation ability of the hybrid model was tested for a flow over a hump model with no-flow control and steady suction. ASBM-SA model produced satisfactory predictions for the streamwise Reynolds stress component, while a qualitative agreement with the experiments was achieved for the transverse component. Regarding the shear stress component, ASBM-SA closure provides improved predictions compared to SA in the entire domain.
