The second order flux limiter method can be cast in several ways but
is generally expressed in terms of other flux approximations. For
example, in terms of a first order upwind flux and second order
Lax-Wendroff flux, the limited flux is given as:
|
(2.187) |
where is the limiter function,
|
(2.188) |
is the upwind flux,
|
(2.189) |
is the Lax-Wendroff flux and
is the
Courant (CFL) number.
The limiter function, , takes the slope ratio
as it's argument. There are many choices of limiter function but we
only provide the Superbee limiter [45]:
