where should I places the film coefficient?
I have a greenhouse which I have the indoor temperature and air flow, now I want a film coefficient places. but where should I put this?
on the inside where the film coefficient touches the indoor air or the exterior side?
greeting

assuming you are modeling the "wall" of the greenhouse as a 3D solid to account for the conductivity, you should apply the fim coeff on the exterior surface of the wall.
Hi derrek,
the model is not a 3d solid, but is made with walls in revit architecteur. because there are several areas on 1 surface. with different coefficients.
If I solve this with heat transfeur what should I use for convection. natural or forced?

What coefficient would you use?
Is that 0.024 for air?
Say I was modelling an internal flow of water, in say a radiator, but wanted to simulate conduction to the external flow, how would I go about doing it? Would I need both an internal and external flow coefficient?
Cheers
Lots of questions here:
Thanks.
