Grid resolution assessment method for hybrid RANS-LES in turbomachinery [PDF]
Engineering Applications of Computational Fluid Mechanics, 2022 Hybrid RANS-LES is a promising method for analyzing the complex flow structure in turbomachinery due to its excellent compromise between accuracy and computational cost. However, it is challenging to employ the existing URANS and LES grid resolution evaluation approaches in a hybrid RANS-LES simulation, thus commonly the required grid resolution is ...
