On direct inverse of Stokes, Helmholtz and Laplacian operators in view of time-stepper-based Newton and Arnoldi solvers in incompressible CFD
Stoke Helmholtz Laplacian operators time-stepper-based Newton Arnoldi solvers incompressible CFD

Abstract: Factorization of the incompressible Stokes operator linking pressure and velocity is revisited. The main purpose is to use the inverse of the Stokes operator with a large time step as a prec...
Thermodynamically Consistent Diffuse Interface Models for Incompressible Two-Phase Flows with Different Densities
Diffuse Interface Models Incompressible Two-Phase Flows Different Densities
2010/11/12
A new diffuse interface model for a two-phase flow of two incompressible fluids with different densities is introduced using methods from rational continuum mechanics. The model fulfills local and gl...
An efficient method for the incompressible Navier-Stokes equations on irregular domains with no-slip boundary conditions, high order up to the boundary
the incompressible Navier-Stokes equations irregular domains no-slip boundary conditions
2010/11/18
Common efficient schemes for the incompressible Navier-Stokes equations, such as projection or fractional step methods, have limited temporal accuracy as a result of matrix splitting errors, or introd...
Passive tracer patchiness and particle trajectory stability in incompressible two-dimensional flows
Passive tracer patchiness particle trajectory stability two-dimensional flows
2009/11/11
Particle motion is considered in incompressible two-dimensional flows consisting of a steady background gyre on which an unsteady wave-like perturbation is superimposed. A dynamical systems point of v...
Least-Squares Mixed Finite Element Methods for the Incompressible Magnetohydrodynamic Equations
2007/12/12
Least-squares mixed finite element methods are proposed and analyzed for the incompressible magnetohydrodynamic equations, where the two vorticities are additionally introduced as independent variable...
