Sergei K. Godunov is credited with introducing the first exact Riemann solver for the Euler equations, by extending the previous CIR (Courant-Isaacson-Rees) method to non-linear systems of hyperbolic conservation laws. Modern solvers are able to simulate relativistic effects and magnetic fields. More recent research shows that an exact series solution to the Riemann problem exists, whic… Nettet3. jul. 2024 · An improved version of a previously validated linearized Euler equation solver is used to compute the noise generated by coannular supersonic jets.
