Non-zonal detached eddy simulation coupled with a steady RANS solver in the wall region

Xiao and Jenny (2012) proposed an interesting hybrid LES/RANS method in which they use two solvers solve the RANS LES equations entire computational domain. In present work this is simplified used as a RANS-LES method, wall-modeled LES. The are employed Near walls, flow governed by steady solver; drift terms added to DES ensure that time-averaged fields agree with field. Away from region, field set disadvantage of traditional models near-wall region – originally were developed tuned for URANS where large part turbulence resolved. context developed. standard methods, accuracy can be degraded unsteady agitation coming region. It may worth while accurate, advanced model. EARSM model solver. new called NZ S-DES . found substantially improve predicting capability DES. A great advantage it insensitive location interface. • Two wall Drift equations.
