Link-wise artificial compressibility method
Nettet1. jul. 2016 · The link-wise artificial compressibility method (LW-ACM), introduced in [1], is a novel approach for solving the incompressible Navier–Stokes equations on Cartesian grids. Asymptotic analysis demonstrates that the LW-ACM yields the artificial compressibility equation [2], first proposed by Chorin in 1967. Nettet3. mai 2024 · We investigate artificial compressibility (AC) techniques for the time discretization of the incompressible Navier-Stokes equations. The space discretization is based on a lowest-order face-based scheme supporting polytopal meshes, namely discrete velocities are attached to the mesh faces and cells, whereas discrete pressures are …

Nettet20. nov. 2010 · The artificial compressibility method, as shown by Equation (2.28), results in a system of hyperbolic-parabolic equations of motion. Physically, this means that waves of finite speed are introduced into the incompressible flow field as a medium to distribute the pressure. Nettet2. okt. 2015 · To this end, we present an extension to the link-wise artificial compressibility method (LW-ACM) for thermal simulation of weakly compressible flows. The novel hybrid formulation uses second-order finite difference operators of the energy equation based on the same stencils as the LW-ACM.
