Numerical Method for Unsteady Seepage Flow Problems with Phreatic Surface Using HPM

Numerical Solution of an Unsteady Flow Using Artificial Compressibility Method

The work presents an artificial compressibility method applied to incompressible Navier-Stokes equations for steady as well as for unsteady flows. Two modifications of unsteady numerical solution by an implicit finite volume method are considered. First one uses large artificial compressibility parameter and the iterative solution approximates unsteady evolution of flow. The second approach int...

Numerical Simulation of Seepage Flow through Dam Foundation Using Smooth Particle Hydrodynamics Method (RESEARCH NOTE)

In this paper, a mesh-free approach called smooth particle hydrodynamics (SPH) is proposed to analyze the seepage problem in porous media. In this method, computational domain is discredited by some nodes, and there is no need for background mesh; therefore, it is a truly meshless method. The method was applied to analyze seepage flow through a concrete dam foundation. Using the SPH method, the...

Numerical Tools for Unsteady Viscous Flow Control

Abstract: This paper reports about progress in the development of numerical tools for adaptive aerodynamic configuration design. We try to illustrate the use of new software components allowing for the parameterized modelling of boundary conditions and the simulation of compressible steady and unsteady viscous flows including a computational flow control model. A coupling of these tools and the...
