I want to find the distribution of Nusselt number on a wall which have constant heat flux boundary condition. My calculation case is like the air flow in a channel that have one side is heated wall and other sides are adiabatic wall. Since I use low k-ep model, so I can suppose that the air temperature in the calculation mesh next to the heated wall can be use instead the temperature on wall. So, in my case, the nusselt number can be calculated from equation like : Nu = heat flux / ( T(mesh next to wall) - T(ref.) ) Is it possible to use In-form to define new variable to calculate Nusselt number in q1 file??

Thank you.
