Two-scale numerical simulation of the weakly compressible 1D isentropic Euler equations
This work addresses the numerical difficulty of solving weakly compressible flows for researchers in computational fluid dynamics.
The authors developed a two-scale numerical method for solving weakly compressible 1D isentropic Euler equations, demonstrating improved accuracy as the Mach number decreases.
Motivated by the difficulty to solve numerically the weakly compressible 1D isentropic Euler equations with classical methods, we develop in this paper a two scale numerical method on this model. This method is based on two scale convergence theory developped by N'Guetseng and Allaire, and finite volume scheme. Furthermore, we do some numerical simulations in order to verify that the two-scale numerical method is more and more accurate when the Mach number diminishes.
