OpenFOAM Tutorial Standard Solvers

rhoPimpleFoam

= = = = = = = = = =

Transient solver for turbulent flow of compressible fluids for ventilation and heat-transfer

Example Problem: angledDuct a simple mesh of a duct that is bent at an angle, gas is thrust through the inlet and makes its way to the outlet while heating the mesh as well

rhoPorousSimpleFoam

= = = = = = = = = = = = = =

Steady-state solver for turbulent flow of compressible fluids with implicit or explicit porosity treatment

Example Problems: angledDuctExplicit duct with a rectangular cross section with a sharp 45_ bend

at the center. The porous media is added where the duct is bending and it goes halfway up the angled duct

angledDuctImplicit same as the other solver, the difference is the porosity of examples, this example has a finer mesh, and therefore is far more robust

rhopSonicFoam

= = = = = = = = = =

Pressure-density-based compressible flow solver

Example Problems: shockTube a one dimensional unsteady case where a discontinuity,

normally in pressure, is introduced in the middle of the domain

wedge15Ma5 same as the first wedge case, without the upward scheme, as the solver is also pressure based

rhoSonicFoam

= = = = = = = = =

Density-based compressible flow solver

Example Problems: forwardStep same as the first forward step without the applied upward scheme shockTube same tube and solver again, however this one is neither pressure or central-upwind scheme based

rhoTurbFoam

= = = = = = = = =

Transient solver for compressible, turbulent flow

Example Problem: cavity the same as the icoFoam case however this isn’t a laminar flow, as well the lid is no longer the transient side but the back wall

rhoTurbTwinParcelFoam

= = = = = = = = = = = = = = = =

Transient solver for compressible, turbulent flow with two thermo-clouds

Example Problem: simplifiedSiwek multiregion lagrangian clouds, in a squar 2D mesh with a long inlet in the top left corner, shows turbulent flow into compression of the gas

scalarTransportFoam

= = = = = = = = = = = = = =

Solves a transport equation for a passive scalar

Example Problem: pitzDaily scalar transport, swirl test: non-uniform initial field, using

field algebra

settlingFoam

= = = = = = = =

Solver for 2 incompressible fluids for simulating the settling of the dispersed phase

Example Problems: dahl a very fine 2D mesh in which two 2 fluids are released, one one from the top and the other from the bottom, they then settle together tank3D Couldn’t find anything

simpleFoam

= = = = = = = =

Steady-state solver for incompressible, turbulent flow of non-Newtonian fluids

Example Problems: airFoil2D a 2D airfoil in a large square mesh, that is put into the flow

of turbulent non-Newtonian fluids

pitzDaily same as all the others, however this version has a turbulent flow pitzDailyExptInlet same thing with a different inlet

simpleSRFFoam

= = = = = = = = = =

Steady, incompressible, rotating reference frame

Example Problem: mixer a large 3D rotor, can be applied in many different ways

snappyHexMesh

= = = = = = = = = = Automatic meshing tool

Example Problems: iglooWithFridges motorBike

exactly as advertised, an igloo with 2 fridges in it, simply used to show how the tool works

once again, simply here to show how the tool works

solidDisplacementFoam

= = = = = = = = = = = = = = =

Transient segregated finite-volume solver of linear-elastic, small-strain deformation of a solid body, with optional thermal diffusion and thermal stresses

Example Problem: plateHole a square mesh with a quarter circle cut out of the bottom left corner, pressure is applied to the plate for stress analysis

solidEquilibriumDisplacementFoam

= = = = = = = = = = = = = = = = = = = = = =

Steady-state segregated finite-volume solver of linear-elastic, small-strain deformation of a solid body

Example Problem: beamEndLoad a rectangular beam is strained, testing the elastic properties of the material, as well stress is shown in the beam

sonicFoam

= = = = = = =

Transient solver for trans-sonic/supersonic, laminar flow of a compressible gas.

Example Problems: forwardStep same as the other forwardStep problems, however this contains a laminar flow rather than turbo shockTube another version of a shock tube problem with a laminar flow and compressible gas

sonicLiquidFoam

= = = = = = = = = = =

Transient solver for trans-sonic/supersonic, laminar flow of a compressible liquid

Example Problem: decompressionTank a simple tank under high pressure becomes decompressed by a nozzle inserted in the side of the tank

sonicTurbFoam

= = = = = = = = = =

Transient solver for trans-sonic/supersonic, turbulent flow of a compressible gas

Example Problems: nacaAirfoil a supersonic flow around a 2D NACA airfoil prism a supersonic flow blown around a 2D prism

turbFoam

= = = = = =

Transient solver for incompressible, turbulent flow

Example Problem cavity same as the last cavity case, however it contains incompressible gas

twoPhaseEulerFoam

= = = = = = = = = = = = =

Solver for a system of 2 incompressible fluid phases with one phase dispersed, e.g. gas bubbles in a liquid

Example Problems: bed couldn’t find anything bed2 couldn’t find anything bubbleColumn couldn’t find anything
