Can "pipe(G)" block be used to model forced air convection?

Hello,
i am trying to model a battery pack with forced air convection cooling. The pipe(G) block can be used to transfer heat from gas flowing inside a pipe to intended surface geometry. But it is internal flow. My concern is i want to model heat transfer from the surface to the gas(air). But that will become external flow problem. Is it possible to do so?
please help!
thanks.

I think it's possible. The combination of cross section and hydraulic diameter will give you a circumference; that multiplied by the pipe length is the total heat transfer area. So I would say it's possible.

If the heat transfer is happening between the air gap and the cell wall, I think the perimeter should be 2*3*h in your equation.

But, keep in mind, this is an approximation at best, because I think your formulation is more appropriate for "cubic" shape cells. The gap shown in the picture is really the minimum gap.
