Question
Consider transient heat conduction in a plane wall with variable heat generation g(x.t)= q=(x,t ) and constant thermal conductivity. The nodal network of the medium consists of nodes 0, 1, 2, and 3 with a uniform nodal spacing of delta x: The wall is initially at a specified temperature The temperature at the right boundary (node 4) is specified. Using the energy balance approach, obtain the explicit finite-difference formulation of the boundary node 0 for the case of combined convection, radiation, and heat flux at the left boundary with an emissivity of epsilon convection coefficient of h, ambient temperature of Tx, surrounding temperature of T ser and uniform heat flux of q0= qwall toward the wall. Also, obtain the explicit finite-difference formulation for nodes 1, 2 and 3.Explanation / Answer
Hello. We cramster experts have decided not to provide any answer publicly. That is because people are copying from older threads which have public answers. Hence we'll only send the answer after you rate. So please rate a Lifesaver and I'll send the solution to your inbox or email. You've got no other option to get the answer, because no one is going to give you the answer over here. You need not worry as I have the solution ready in my notebook. Hope you rate me :)
