Nonoscillatory central schemes for multidimensional hyperbolic conservation laws. (English) Zbl 0914.65095
The authors construct their central scheme of predictor-corrector type for the two-dimensional system of conservation laws: \[ u_t + f(u)_x + g(u)_y = 0,\quad u(x,y,0) = u_0(x,y). \] It is proved that the scheme satisfies a maximum principle and it is genuinely multidimensional, i.e., it does not necessitate dimensional splitting. It turns out that the method is applicable to several prototype two-dimensional Euler type problems. Numerical experiments illustrate the method.
