Thermal_engg Member Prateek Anand Join Date: Nov 2012 Posts: 34 Rep Power: 13	Hey everyone, I am modelling a rectangular natural circulation loop with isothermal heat source and heat sink and the rest of the surfaces are adiabatic.This whole system is isolated from the surroundings.I am using carbon dioxide as a fluid inside the loop. My question is that IS there any way to simulate this model in Fluent without specifying laminar or turbulent flow.It is not known beforehand what type of flow will take place . Any help is appreciated.Thnx
