1D Thermo-Chemical Analysis • In general, the curing process can be divided into two steps: – Heat-up step: As the autoclave is heated, the heat is transferred to the centre of the part first through convection at the boundary of the part and then through conduction: – Polymerization step: at some point, due to the external heat, polymerization reaction starts in the part.
I am trying to solve a transient heat transfer problem. The problem is that I have an insulated pipe that is immersed in cold water. At time 0, the fluid filling the pipe is at a constant temperature. The insulation at one end of the pipe is different to the rest of the insulation.
Problems are solved using four popular software, viz. “Mathcad”, “Engineering Equation Solver (EES)” , “Finite Element Heat Transfer (FEHT)” and MS EXCEL-2007. Comments are included generously in the codes so that the logic behind the solution is clear.
