hello to all.
im trying to read the nusselt number in a internal laminar flow with Re=200. i have constant heat flux condition on the walls. in the reference values i give the diameter and the inlet temperature. when i plot the nusselt number on the wall, i see it starts about 20, comes down, and when i make the length longer, at last it reaches near zero! why???
can anybody help me out?
