I am simulating convective heat transfer of turbine blade to get areodynamic heat from flow. I have give boundary as Adiabatic。
I post-process results, get this:
1. local heat transfer coefficient = 5000,
2.Specified Y+ Heat Transfer Coefficient = 100-500.
3. Heat Transfer Coefficient =0.

Could any one explain Specified Y+ Heat Transfer Coefficient?
1. Is it proper to use Adiabatic boundary condition?
2. Is it reasonable to use Adiabatic boundary condition and Specified Y+ Heat Transfer Coefficient for my blade conductive heat transfer?
3. from my view, when i set Adiabatic boundary condition, the heat flux on wall shall be 0, and Heat Transfer Coefficient also be zero, so why is Specified Y+ Heat Transfer Coefficient and local Specified Y+ Heat Transfer Coefficient is not zero?
4. If i want to compare my result with my experiment, in which i get h by Tref as my inlet Temperature, how can i compare it?

Thanks a lot.
