Abstract: | The application of the optimized dispersion relation preserving scheme (DRP-scheme) in combination with the explicit optimized
two-layer Runge-Kutta scheme is presented to solve a system of one-dimensional and quasi-one-dimensional Euler equations using
as an example the solution of four test problems, namely, discontinuity disintegration in a tube (Sod’s problem); transfer
of the lowamplitude Gaussian pulse; acoustic wave propagation through the transonic nozzle; acoustic wave-shock interaction.
Also given are the comparison of the calculation results using different schemes: DRP, CABARET, CE-SE and the standard Lax-Wendroff
schemes as well as the solutions obtained with the use of software packages. |
