Amirhossein mokhtari New Member Join Date: Apr 2017 Posts: 2 Rep Power: 0	Hello everybody. I tried to find the Nusselt number in flat channel with constant wall temperature by ANSYS Workbench. Thermally developing condition is governed! But the Nusselt number which is obtained by ANSYS is not equal to the one which is existed in the books, when the flow is developed.(Consequently before that) I defined the Nusselt number by Nu = hx/k = qx/k(Tw-Tm) in CFD post after defining the Tm by Line Integral operation. What is wrong? Geometry, Meshing, B.Cs, Reference Values or other? PLEASE HELP ME.
