Contributed solvers

1 Solvers that fit into the OpenFOAM classification

These solvers fit into the classification, that is given by the directory structure of the solver-sources.

1.1 basic

1.2 combustion

1.3 compressible

1.4 DNSandLES

1.5 electromagnetics

1.6 financial

2 heatTransfer

2.1 Problem setup

The problem studied is a hot air flow injected into a container coupled with the heat transfer from the flow to and into the container walls. Numerically, this is solved in a Large Eddy Simulation framework, with a one equation transport model for the subgrid turbulent kinetic energy.

3 Complete Solution

The first approach was to take into account both domains, and to solve two different sets of equations:

3.1 Compressible fluid flow

$\frac{\partial\rho}{\partial t}+\nabla\cdot\rho U=0$

$\frac{\partial\rho U}{\partial t}+\nabla\cdot\phi U-\nabla\cdot\mu\nabla U=-\nabla p$

$\frac{\partial\rho h}{\partial t}+\nabla\cdot\phi h=0$

3.2 Heat conduction in the solid domain

$\frac{\partial T}{\partial t}+k\cdot\Delta T=0$

Media:conjHeat.tgz. The test case consists in a solid can (see Figure 1b), in which a hot fluid (700 K) is injected with 0.1m/s through a small area (green face in Figure 1a). The exterior wall surface of the can is kept at a constant temperature of 300 K. File:P1.png

3.3 incompressible

3.4 multiphase

3.5 stressAnalysis

4 Other

These solvers don't fit into the standard scheme.

4.1 Technology Demos

Solvers that demonstrate concepts, but haven't got a fully implemented physics.

icoLagrangianFoam Incompressible solver with particles. Demonstrates the use of Lagrangian-particles outside the dieselFoam solver

icoStructFoam Fluid-Structure interaction. Demonstrates the use of two coupled solvers and mesh motion

Note to editors: Use the solver name as the page name, when adding a new solver to this page, but prepend custom in order to avoid name clashes
