A Numerical Solution to a Free Surface Wave Problem

The aim of this paper is to present a numerical method for the calculation of water waves in a semi-infinite wave tank. The motion of the fluid, which is assumed to be inviscid, is caused by the motion of part of the boundary of the basin. The correct numerical simulation of the interaction between the side walls and the fluid is an intrinsic feature of the problem. In the literature a series o...

Free and constrained equilibrium states in a variational problem on a surface

We study the equilibrium states for an energy functional with a parametric force field on a region of a surface. Consideration of free equilibrium states is based on Lyusternik - Schnirelman's and Skrypnik's variational methods. Consideration of equilibrium states under a constraint of geometrical character is based on an analog of Skrypnik's method, described in [P. Vyridis, {it Bifurcation in...

Numerical Simulation of Free Surface in the Case of Plane Turbulent Wall Jets in Shallow Tailwater

Wall-jet flow is an important flow field in hydraulic engineering, and its applications include flow from the bottom outlet of dams and sluice gates. In this paper, the plane turbulent wall jet in shallow tailwater is simulated by solving the Reynolds Averaged Navier-Stokes equations using the standard  turbulence closure model. This study aims to explore the ability of a time splitting method ...

Numerical analysis of a free piston problem ∗

The problem considered is the Stokes and Navier-Stokes flow through a system of two pipes in the gravity field; inside a vertical pipe there is a free heavy piston. Theoretical analysis, the existence and non-uniqueness of solution, has been completed recently by the authors. Here we present numerical analysis, using finite elements methods, of the stationary state with respect to the angle bet...

Numerical Simulation of Free Surface Flows and Comparison of Symmetry and Real Boundary Conditions at the Free Surface

For implementation&#10 of the free surface boundary condition, a new subroutine has been introduced to an existing steady 3-D body fitted code. This code was previously written for steady flow simulation in closed ducts. The algorithm used in this subroutine reduces the instability problem according to the free surface wave generation. For code validation, it was applied to two different open c...
