Dear my friends
I have modeled laminar flow in a 3D channel with following B.Cs: inlet:velocity inlet, outletressure outlet and other boundaries:wall(constant heat flux).
I want to plot local Nusselt number along the channel.
Nu(z)=q"/[Tw(z)-Tm(z)] where Tm(z) is local mean fluid temperature i.e. Tm=int[T(x,y).W(x,y)]/int[W(x,y)]. z is streamwise and x,y are spanwise directions and W is axial velocity.
How can I plot Nu(z)-z curve?
