Numerical analysis of convective heat transfer in a triangular duct with radiation boundary conditions

Finite difference has been used to model a laminar, fully developed flow through a isosceles triangular duct with based fully insulated and the other two sides subjected to radiation boundary condition. Taking into account on practical application in the industries, radiation boundary conditions are...
