| Abstract: | The numerical solutions of one dimensional unsteady convective heat transfer (one dimensional advection equation with a source term) are investigated. It is indicated by the analysis that there is a matching problem between time and geometric steps for the explicit scheme and it is suited to computation of a transient process, while the implicit scheme is suited to computation of a quasi-steady process. |
