Backflow in Domain
suppose i have backflow in my domain at pressure outlet ,
so is there any method to determine the backflow turbulence quantities like intensity and all ?
Will solution general flow field be susceptible to these backflow quantities ?
How to approach modelling backflow in domain provided i am no position to increase domain length to negate this backflow to forward flow only. ? If not possible then how much minimum length increase is required , is there any method to quantify ?
