XXII ICTAM, 25–29 August 2008, Adelaide, Australia ON PENALTY APPROACHES FOR NAVIER-SLIP AND OTHER BOUNDARY CONDITIONS IN VISCOUS FLOW

چکیده
With the advent of microscale and nanoscale devices, the Navier-slip boundary condition as a macroscale model of fluid behaviour at a solid wall has seen renewed interest. The penalty concept and variational formulation are extended here to treat partial slip and related boundary conditions in viscous flow simulation. An analysis of the penalty partial-slip formulation permits us to relate it to the classical Navier slip condition and easily embed this class of boundary conditions in existing finite element flow software.

A Unified Wall Boundary Treatment for Viscous and Inviscid Flows in the CE/SE Method
Abstract. In the setting of the CE/SE method, a new and unified wall boundary treatment for the Navier-Stokes and Euler Equations is proposed. In essence, the shear stress exerted on the fluid by a wall is modeled as a source term as a part of local space-time flux conservation in the vicinity of a wall boundary. When the fluid is inviscid, the source term vanishes and the boundary condition re...
متن کاملTransitional cylindrical swirling flow in presence of a flat free surface
This article is devoted to the study of an incompressible viscous flow of a fluid partly enclosed in a cylindrical container with an open top surface and driven by the constant rotation of the bottom wall. Such type of flows belongs to a group of recirculating lid-driven cavity flows with geometrical axisymmetry and of the prescribed boundary conditions of Dirichlet type—no-slip on the cavity w...
متن کاملSimulation of Pitching and Heaving Airfoil with Oscillation of Flow Boundary Condition
A pressure based implicit procedure to solve the Euler and Navier-Stokes equation is developed to predict transonic viscous and inviscid flows around the pitching and heaving airfoils with a high reslution scheme. In this process, nonorthogonal and non moving mesh with collocated finite volume formulation are used. In order to simulate pitching or heaving airfoil, oscillation of flow boundary c...
متن کاملHelmholtz decomposition coupling rotational to irrotational flow of a viscous fluid.
In this work, I present the form of the Navier-Stokes equations implied by the Helmholtz decomposition in which the relation of the irrotational and rotational velocity fields is made explicit. The idea of self-equilibration of irrotational viscous stresses is introduced. The decomposition is constructed by first selecting the irrotational flow compatible with the flow boundaries and other pres...
متن کاملAn optimal order interior penalty discontinuous Galerkin discretization of the compressible Navier-Stokes equations
In this article we propose a new symmetric version of the interior penalty discontinuous Galerkin finite element method for the numerical approximation of the compressible Navier-Stokes equations. Here, particular emphasis is devoted to the construction of an optimal numerical method for the evaluation of certain target functionals of practical interest, such as the lift and drag coefficients o...
