Abstract:
A new formulation of the Godunov scheme with linear Riemann problems is proposed that guarantees a nondecrease in entropy. The new version of the method is described for the simplest example of one-dimensional gas dynamics in Lagrangian coordinates.
Key words:
fluid dynamics equations, computation of discontinuous solutions, Godunov's scheme, entropy nondecrease guarantee.
