Pseudo-characteristic upwind scheme for incompressible flows

Three-dimensional characteristic approach for incompressible thermo-flows and influence of artificial compressibility parameter

In this paper the characteristics of unsteady three-dimensional incompressible flows with heat transfer are obtained along with artificial compressibility of Chorin. At first, compatibility equations and pseudo characteristics for three-dimensional flows are derived from five governing equations (continuity equation, Momentum equations in three directions, and energy equation) and then results ...

An Upwind-Differencing Scheme for the Incompressible Navier-Stokes Equations

A Fast Immersed Boundary Fourier Pseudo-spectral Method for Simulation of the Incompressible Flows

Abstract   The present paper is devoted to implementation of the immersed boundary technique into the Fourier pseudo-spectral solution of the vorticity-velocity formulation of the two-dimensional incompressible Navier-Stokes equations. The immersed boundary conditions are implemented via direct modification of the convection and diffusion terms, and therefore, in contrast to some other similar ...

Parallel Overlapping Scheme for Viscous Incompressible Flows

A 3D parallel overlapping scheme for viscous incompressible flow problems is presented that combines the finite element method, which is best suited for analysing flow in any arbitrarily shaped flow geometry, with the finite difference method, which is advantageous in terms of both computing time and computer storage. A modified ABMAC method is used as the solution algorithm, to which a sophist...

Application of a Pseudo Penalization Method for Incompressible Unsteady Flows

Application of a Pseudo Penalization Method for Incompressible Unsteady Flows Computational fluid dynamics is an extensive research area since the fluid flows have vital importance in large number of applications in today’s engineering world. This thesis report presents an application of a new method which is developed to compute the solutions of incompressible flows around bluff bodies. This s...
