Simulation of Three Phase Flow in Porous Media Using a High-Resolution Central Scheme

This article aims to demonstrate the advantages of using a high resolution central scheme in the field of multiphase flow in porous media. The black oil model, used in the petroleum reservoir engineering, is employed as it generally provides an acceptable model for most reservoirs and recovery processes. The governing equations are split into a...

Model and full-scale free-surface viscous flows around fully-appended ships

Two appended hull configurations have been simulated using all hexahedral unstructured grids. Numerical uncertainty is assessed with grid refinement. Influence of turbulence model and wall function approach have also been investigated. Scale effect is also studied for one configuration. Numerical results are validated both with measurement data...

A three-dimensional finite volume method for incompressible Navier-Stokes equations on unstructured hybrid staggered grids

In this work, a new method was described for spatial discretization of threedimensional Navier Stokes equations in their primitive form, on unstructured, staggered grids. Velocities were placed on the cell faces and pressure in cell centers and were linked with the projection method. Thanks to the variable arrangement, no stabilization procedure...

Domain Decomposition Approach for Automatic Parallel Generation of 3D Unstructured Grids

The desire to simulate more and more geometrical and physical features of technical structures and the availability of parallel computers and parallel numerical solvers which can exploit the power of these machines have lead to a steady increase in the number of grid elements used. Memory requirements and computational time are too large for...

Unstructured periodic grid generation around 2D turbine cascades

A novel grid generation algorithm for periodic unstructured grid around two-dimensional highly-staggered turbine cascades, including multiply connected blade geometries, is presented. The idea is to generate the mesh in a transformed space in which the periodic boundaries are coincident and internal to the computational domain so that no special...
