The present paper deals with the improvement of a QUICK scheme for the resolution of convection–diffusion problems. In order to avoid any unstability problems and to increase the convergence speed a new deferred correction is suggested. Checking the required stability criteria, benefits are taken from the accuracy of the central difference scheme when it is possible. Otherwise, a upwind scheme is...
This paper is devoted to transient heat transfer involving radiation and conduction. Considering a non-gray purely absorbing media, the radiative heat transfer equation (RTE) is solved iteratively with the Discrete Ordinates Method (DOM) using an exponential differencing scheme. The energy balance equation is used to compute temperature at each time step with the Crank–Nicholson technique. Energy...
