Hi
I am new to fluent trying to learn ansys by some simple cases
My problem is simple a circular pipe with inlet velocity 0.5m/s and temperature is 15c wall thickness is zero(only fluid domain) (laminar flow) constant wall temperature is 500 K pressure outlet is zero pascal.how to calculate the heat transfer coefficient and nusselt number for this flow?

How to plot nusselt number vs direction vector (in flow direction) because nusselt number changes in thermal entry length? and how to plot the heat transfer coefficient along the flow direction ?

Thanks
Naruto
