Computation of Discontinuous Solutions of Fluid Dynamics Equations with Entropy Nondecrease Guarantee
Computational mathematics and mathematical physics(2014)
摘要
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.
