Web27 Jul 2010 · The temperature profile for the constant heat flux at the wall can be used as the first approximation, and eq. (35) is then integrated to obtain θ. This iterative procedure is repeated until an acceptable convergence is obtained. However, in order to get a very good accuracy, a forth-order Rung-Kutta procedure is employed to solve eq. (35). WebA plane wall is constructed of solid iron with thermal conductivity 70 W/moC. Thickness of the wall is 50 mm and surface length and width is 1 m by 1 m.
