Numerical Simulation of Incompressible Magnetohydrodynamic Flows
This paper presents numerical simulations of incompressible fluid flow problems in the presence of a magnetic field. The equations governing the flow consist of the Navier-Stokes equations of fluid motion coupled with Maxwell ́s equations of electromagnetics. The study of fluid flows under the influence of a magnetic field and with no free electric charges or electric fields is known as magnetoh...
متن کاملAnalysis and shape optimization in incompressible flows with unstructured grids
The aim of this study is to develop and validate numerical methods that perform shape optimization in incompressible flows using unstructured meshes. The three-dimensional Euler equations for compressible flow are modified using the idea of artificial compressibility and discretized on unstructured tetrahedral grids to provide estimates of pressure distributions for aerodynamic configurations. ...
متن کاملSimulation of Gravity Wave Propagation in Free Surface Flows by an Incompressible SPH Algorithm
This paper presents an incompressible smoothed particle hydrodynamics (SPH) model to simulate wave propagation in a free surface flow. The Navier-Stokes equations are solved in a Lagrangian framework using a three-step fractional method. In the first step, a temporary velocity field is provided according to the relevant body forces. This velocity field is renewed in the second step to include t...
متن کاملA 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 ...
متن کاملVariational Multiscale Large Eddy Simulation of Turbulent Incompressible Flows
The variational multiscale (VMS) method was introduced in [4] as a framework for the development of stabilization techniques, which aim to overcome numerical difficulties encountered when using the standard Galerkin method, the finite element (FE) counterpart of centered finite differences (FD), namley, the compatibility condition between the velocity and pressure FE spaces, which require the u...
