A fast vector penalty-projection method for incompressible non-homogeneous or multiphase Navier-Stokes problems
We present a new fast vector penalty-projection method (VPPε) to efficiently compute the solution of unsteady NavierStokes problems governing incompressible multiphase viscous flows with variable density and/or viscosity. The key idea of the method is to compute at each time step an accurate and curl-free approximation of the pressure gradient increment in time. This method performs a two-step ...
متن کاملA Spectacular Vector Penalty-Projection Method for Darcy and Navier-Stokes Problems
We present a new fast vector penalty-projection method (VPPε ), issued from noticeable improvements of previous works [7, 3, 4], to efficiently compute the solution of unsteady Navier-Stokes/Brinkman problems governing incompressible multiphase viscous flows. The method is also efficient to solve anisotropic Darcy problems. The key idea of the method is to compute at each time step an accurate ...
متن کاملA finite element penalty-projection method for incompressible flows
The penalty–projection method for the solution of Navier–Stokes equations may be viewed as a projection scheme where an augmentation term is added in the first stage, namely the solution of the momentum balance equation, to constrain the divergence of the predicted velocity field. After a presentation of the scheme in the time semi-discrete formulation, then in fully discrete form for a finite ...
متن کاملPenalty-projection Method for a Monolithic Fluid Structure Interaction Solver
Abstract. In this paper we present the results of Fluid-Structure Interaction (FSI) computations of an incompressible solid object and laminar incompressible viscous flows using a combined penalty-projection algorithm. The system consists of a fluid region governed by Navier-Stokes equations and a solid domain described by elastic and hyperelastic structure mechanical equations. In particular w...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
