Stress-Blended Eddy Simulation of the Turbulent Flow Around Circular Cylinder with Dynamic Hybrid RANS/LES Model
|
摘要
In order to verify the effectiveness and superiority of the dynamic hybrid RANS/LES( DHRL) model,the flow around a cylinder with sinusoidal fluctuating velocity at the inlet was used as the test case. The latest computational fluid dynamics( CFD) model can flexibly choose any existing large-eddy simulation( LES) method combined with RANS method to calculate the flow field. In addition,the DLES model and DDES model are selected as typical representatives of the turbulence model to compare the capture ability of the flow field mechanism. The internal flow field including the y + value,velocity distribution,turbulent kinetic energy and vortex structures is comprehensively analyzed. Finally,the results show that the new model has enough sensitivity to capture the information of the flow field and has more consistent velocity distribution with the experimental value,which shows its potential in practical engineering applications to some extent.
