In CFD simulations involving turbulence we are focused on predicting the effect of the turbulent flow rather then the actual fluid flow. Example we are not worried about the eddies which happen on a microsecond timescale but are rather focused on the effect that turbulence will have on flow parameters.

In RANS Model we introduce extra variables like u', v', p' in the flow equations. Many different types of turbulence models provide additional equations which must be satisfied my flow...
