This is a forced convection heat transfer problem and would appreciate any help! Stack of steel billets is placed in a cooling chamber. All billets of the same row are touching each other and each row is spaced of 5 in. I want to calculate the convection coefficient and pressure drop across...

Mapes, It is clearer for me. Thank you for your precise and valuable inputs. I solved the equations using MATLAB (for fun) and I found: 1 node, q = 11,700 W (2 iterations) 11 nodes, q = 10,200 W (115 iterations) 101 nodes, q = 9,935 W (6124 iterations)...

Mapes, Thank you for your inputs. I don't really understand what you mean by solving for T at each node and iterate until the solution converges. Please tell me if I am wrong: solving for T means, T - \frac{T_\mathrm{R}+T_\mathrm{L}}{2}+\frac{dk(T)}...

Solution Hello, Mapes, I would like to continue in developing a discrete equation to solve numerically. What is the next step and what would be the solution of this equation. \frac{dk(T)}{dT}\left(\frac{dT}{dx}\right)^2+k\frac{d^2T}{dx^2}=0 After reading around...
