conjugate heat transfer(AIRFOIL)
 

Hello,

i am trying to simulate conjugate heat transfer for an 2D airfoil(inside slat). i am using k-epsilon turbulence model, incompressible-ideal-gas as material. my objectives are to achieve temperature raise inside the slat, and relevant velocity at the outlet of airfoil. the boundary conditions that i am using are

1) Velocity inlet(for external aerodynamics), 263K.
2) Mass flow rate(internal inlet, inside slat) 373K.

there is proper flow inside the slat, but there is no temperature rise as desired.

please help me out, is there anything wrong with my boundary conditions?
