yes the party was nice !!!! :D good music, good herbs, sexy girls...:cool:
but unfortunately for you cfdnewbie you lef the party too early :p

The ironic part of this discussion is that in my field of research I am probably better off doing no simulations and just waiting for better algorithms and computers. Ok that sounds good, perhaps computers are better tomorrow morning. Good Night ;)

Reason for using turbulence modeling
 

Turbulence modeling is the construction and use of a mathematical model to predict the effects of turbulence. Turbulent flows are commonplace in most real life scenarios, including the flow of blood through the cardiovascular system, the airflow over an aircraft wing, the re-entry of space vehicles, besides others. In spite of decades of research, there is no analytical theory to predict the evolution of these turbulent flows. The equations governing turbulent flows can only be solved directly for simple cases of flow. For most real life turbulent flows, CFD simulations use turbulent models to predict the evolution of turbulence. These turbulence models are simplified constitutive equations that predict the statistical evolution of turbulent flows. That's why we use it. I learned about this at a party sound & lighting hire company as odd as it seems.
