The convection coeff. depends on geometry and not on heater material. If
your making a micro-hotplate for instance the convection coeff. will
depend on surface area and other geometric details. For our hotplates we
use h=125 W/m2*K for the top surface and  h=60 W/m2*K for bottom
surfaces.

Hi

CFD simulation would give the boundary conditions for your model.
 Sometimes, even thermal analysis in CFD alone can give the sufficient

information.  So, you may not need convection coefficient (natural or
?).
