Combination of high and low Reynolds number
 

Hi,

I am using Fluent to simulate a domain that is formed by 2 parts, one of them has a laminar regime and the other one a tubulent regime, my question is how can I simulate both of them specifying that the kappa-epsilon solver is just going to be applied to the volume that represent the turbulent flow? I heard I could specify the one with the low reynolds number as a laminar zone but I don't know exactly how?

thanks,
