temperature Periodic boundary condition
 
hello friends
Recently I saw a set of equations for periodic boundary condition in turbulent flow. my question is about temperature periodic boundary condition. I found that in this type, we need to pin a temperature value in boundaries to find real amount of temperatures. but what is the theory behind of this? and this value should be set at which point?
thanks a lot
