A Hybrid Adaptive Low-Mach-Number/Compressible Method for the Euler Equations
This paper presents a novel hybrid method for solving the low-Mach-number equations for inviscid flow supplemented with long wavelength acoustics as computed by solving the fully compressible Euler equations. Contrary to previous existing methods, the novelty of the present strategy is that the fully compressible equations are solved without any approximation, and that an adaptive mesh refineme...
متن کاملA hybrid pressure–density-based algorithm for the Euler equations at all Mach number regimes
In the present work, we propose a reformulation of the fluxes and interpolation calculations in the PISO method, a well-known pressure-correction solver. This new reformulation introduces the AUSM up flux definition as a replacement for the standard Rhie and Chow method of obtaining fluxes and central interpolation of pressure at the control volume faces. This algorithm tries to compatibilize t...
متن کاملA Weakly Asymptotic Preserving Low Mach Number Scheme for the Euler Equations of Gas Dynamics
We propose a low Mach number, Godunov-type finite volume scheme for the numerical solution of the compressible Euler equations of gas dynamics. The scheme combines Klein’s non-stiff/stiff decomposition of the fluxes (J. Comput. Phys. 121:213-237, 1995) with an explicit/implicit time discretization (Cordier et al., J. Comput. Phys. 231:56855704, 2012) for the split fluxes. This results in a scal...
متن کاملSolving Hybrid Fuzzy Fractional Differential Equations by Improved Euler Method
In this paper we study numerical methods for hybrid fuzzy fractional differential equations and the iteration method is used to solve the hybrid fuzzy fractional differential equations with a fuzzy initial condition. We consider a differential equation of fractional order and we compared the results with their exact solutions in order to demonstrate the validity and applicability of the method....
