Hi

I have a heat transfer coefficient that I want to apply as a boundary condition to a solid. But because it is a fluid solid interation (thick wall), the shadow appears and I loose the ability to apply a convection condition.

Thanks

Hello,

I have wall as fluid -solid interface means two sided wall. (wall and its shadow wall in FLUENT).

I have a known temperature gradient on that wall and known heat transfer coefficient for convection heat transfer condition.

Wall has solid as its adjacent cell zone and its shadow has gas as its adjacent cell zone.

As I know, temperature gradient can be define using UDF which is constant with respect to time. Now I want heat transfer between solid and gas

with known fixed value of heat transfer co-efficient.

How to define the boundary condition in the above situation in FLUENT...????

Can anyone help me..????????

Thank you...
