OpenFOAM Tutorial Standard Solvers

boundaryFoam

= = = = = = = =

Steady-state solver for 1D turbulent flow, typically to generate boundary layer conditions at an inlet, for use in a simulation

Example Problems:

boundaryLaunderSharma model which has the ability to in model cases and predict

by-pass transition, using the Launder equations.

boundaryWallFunctions solves a 1D turbulent model with two walls and one cyclic

boundaries.

bubbleFoam

= = = = = = = =

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

Example Problem: bubbleColumnclassic bubble column problem with an inlet and outlet for the

foam and bubbles and two walls.

buoyantFoam

= = = = = = = = =

Transient Solver for buoyant, turbulent flow of compressible fluids for ventilation and heat-transfer

Example Problem: hotRoom 3D environment with one inlet, the “floor”, which the user

can make any temperature and watch the thermal effects.

i.e., thermal plume emanating from a 600 degree

source on the floor

buoyantSimpleFoam

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

Steady-state solver for buoyant, turbulent flow of compressible fluids for ventilation and heat-transfer

Example Problem: hotRoom same as the first hot room, however this solver is steady state, showing a longer process, rather than transient.

buoyantSimpleRadiationFoam = = = = = = = = = = = = = = = = = = =

Steady-state solver for buoyant, turbulent flow of compressible fluids with radiation, for ventilation and heat-transfer

Example Problem: hotRadiationRoom a much finer mesh room than the previous two hotRoom

cases, along with an elevated heating source, radiation

channelOodles

Incompressible LES solver for flow in a channel

Example Problem: channel395 solves for channel flow, with several cyclic patches and only two top and bottom walls. Able to keep the mass flow

rate in the channel constant, by calculating the velocity at each step, takes a long time to run.

chtMultiRegionFoam

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

Solver that couples conjugate heat transfer in a solid to a buoyancy-driven flow simulation

Example Problem: multiRegionHeater same as the hotRoom example problems, however this has multiple sources for heat, not just one

compressibleLesInterFoam

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

Solver for 2 compressible, isothermal immiscible fluids using a volume of fluid (VOF) phase-fraction based interface capturing approach, with LES

Example Problems: depthCharge2D modeled on a scale, a charge is blown in the mixture and the turbulence is modeled in a 2D environment based off the run time and a single momentum equation

depthCharge3D same thing as the first, but in a 3D environment.
