there is a problem with fully developed Nusselt number
as you know, Nusselt number for a fully developed laminar flow
in parallel palates should be 7.54 and for example, for kn=0.1 should be 4.75. I have the correct answer for Nusselt number when there is no slip region, but for slip-flow my Nusselt numbers are wrong.
I've checked also slip- flow and heat transfer in rectangular microchannels but as same as parallel plates for the slip region fully developed Nusselt number are wrong but temperature profile is correct.It seems to be all correct except Nusselt number.
i would appreciate for any help.
