Efficient implementation of essentially nonoscillatory shock-capturing schemes. (English) Zbl 0653.65072
Essentially nonoscillatory (ENO) schemes for nonlinear hyperbolic systems have the disadvantage of being very difficult to implement, particularly in more than one spatial dimension or when reaction terms are present in the equation. A new class of ENO schemes is introduced which is much easier to program. The methods use Runge-Kutta time discretizations, and for the representation of the fluxes no cell averages are required. Application of the methods to some standard problems indicates that they work very well in regions near shocks and where the solution is smooth. Near contact discontinuities, however, the methods are excessively diffusive.
