Convection Term

The convective term at a face is discretized as follows:

(340)

where and are the scalar values and mass flow rates at the face, respectively and is the grid flux computed from the mesh motion as in Eqn. 27.

The manner in which the face value is computed from the cell values has a profound effect on the stability and accuracy of the numerical scheme. Several schemes are commonly used:

A description of the computation of the convective flux at a boundary face is also provided in this section.
