UNSTEADY ONE-DIMENSIONAL ADVECTION MODELING USING THE CCMC SCHEME

要約

A new approach, characteristic convective with monotonic conservation (CCMC), is proposed for modeling the advective transport equation. The procedures of the method in solving the pure one-dimensional convective equation are presented. With the construction of the convective characteristic curves for slope and curvature of the convective interpolation in the control volume, these two curves provide a tool to construct a more accurate convective interpolation without phase angle shift. A set of benchmark problems, including three critical test profiles, is used to examine the new scheme.
