... presents a guideline for accurately predicting the performance of centrifugal blowers using compressible flow analysis with large eddy simulation (LES). In LES analysis, it is important to have a grid resolution that resolves the minimum vortex scale near the wall (referred to as wall-resolved LES...

.... With the objective of improving RANS models from large eddy simulation (LES) methods, the volume of fluid (VOF) and Euler–Euler methods for two-phase flow modeling are investigated in this study. The VOF approach assumes a single set of momentum equations for the two phases and volume fractions are 1 or 0 everywhere...

..., and the corresponding relative change in cascade performance was first investigated based on the unsteady Reynolds-averaged Navier–Stokes (uRANS) simulations with/without a transition model. Then, the large eddy simulations in conjunction with the wall-adapted local eddy viscosity model were conducted to investigate...
