Gados571 is on a distinguished road
Dear all,

I'm trying to solve the energy balance equations of a flat plate solar collector components (Glass cover, absorber, air gap and HTF) implicitly in an iterative form. I have discretized all the components' energy balance equations but I'm having doubt for the boundary nodes. All the boundaries are insulated excepted the HTF which has dirichlet boundary condition at the inlet as shown on the attach diagram. Please can someone help me check if I made a mistake and correct me or make suggestion? Thank you.

NB:Attach is the discretization of only one components(Absorber) because the size of the original doc for all the components is big.
