Link-wise artificial compressibility method
The Artificial Compressibility Method (ACM) for the incompressible NavierStokes equations is (link-wise) reformulated (referred to as LW-ACM) by a finite set of discrete directions (links) on a regular Cartesian mesh, in analogy with the Lattice Boltzmann Method (LBM). The main advantage is the possibility of exploiting well established technologies originally developed for LBM and classical co...
متن کاملArtificial compressibility method and lattice Boltzmann method: Similarities and differences
Both the artificial compressibility method and the lattice Boltzmann method yield the solutions of the incompressible Navier-Stokes equations in the limit of the vanishing Mach number. The inclusion of the bulk viscosity is one of the reasons for the success of the lattice Boltzmann method since it removes quickly the acoustic mode, which inevitably appears as the compressible effect, and contr...
متن کاملNumerical Solution of an Unsteady Flow Using Artificial Compressibility Method
The work presents an artificial compressibility method applied to incompressible Navier-Stokes equations for steady as well as for unsteady flows. Two modifications of unsteady numerical solution by an implicit finite volume method are considered. First one uses large artificial compressibility parameter and the iterative solution approximates unsteady evolution of flow. The second approach int...
متن کاملEntropically Damped Artificial Compressibility for SPH
The Entropically Damped Artificial Compressibility (EDAC) method of Clausen [2013] is an interesting alternative to the traditional artifical compressibility technique. We apply the EDAC method in the context of Smoothed Particle Hydrodynamics. In this work we present preliminary results for this method. The method is easy to implement in a standard SPH framework. Our simulations are compared w...
متن کاملArtificial compressibility method revisited: Asymptotic numerical method for incompressible Navier-Stokes equations
The artificial compressibility method for the incompressible Navier-Stokes equations is revived as a high order accurate numerical method (4th order in space and 2nd order in time). Similar to the lattice Boltzmann method, the mesh spacing is linked to the Mach number. The accuracy higher than that of the lattice Boltzmann method is achieved by exploiting the asymptotic behavior of solution of ...
