## Multi-Simulation Heat Exchanger

## Multi-Simulation Heat Exchanger

This tutorial model illustrates how one can couple the OpenFOAM CFD solver with the FEATool Multiphysics FEA solver. In the model a stream of cool air is heated while flowing through a tube and fin heat exchanger. Due to several symmetry planes only a small section of the full heat exchanger geometry actually needs to …

## Modeling of Wind Flow Around Obstructions to Aid Wind Turbine Placement Decisions

## Modeling of Wind Flow Around Obstructions to Aid Wind Turbine Placement Decisions

Renewable energy such as solar and wind power is becoming increasingly important in reducing effects of global warming. The One Energy wind power company installs wind turbines on local properties instead of dedicated wind farms, in which case there are no industry standards how small single obstructions, such as from …

## Turbulent Channel Flow

## Turbulent Channel Flow

Simulation of stationary and incompressible turbulent flow between two parallel flat plates at Reynolds number 42800. A fully developed turbulent velocity profile is formed at the outflow boundary which can be compared to experimental results (Laufer, J. 1950). This example uses both the built-in algebraic mixing …

## Simulation of Heating to Promote Drug Mixing in the Eye

## Simulation of Heating to Promote Drug Mixing in the Eye

The leading cause of central vision loss in the developed world is from age-related macular degeneration (AMD). Although certain types of AMD can generally be managed with injections of anti-VEGF agents, the treatment is sometimes ineffective. The linked study examines how this type of treatment potentially can be …

## Fluid-Structure Interaction - Elastic Beam

## Fluid-Structure Interaction - Elastic Beam

Fluid-structure interaction benchmark problem for stationary, laminar, and incompressible flow around a cylinder with an attached elastic beam. Although it is not possible to derive an analytical solution to these test cases, numerical solutions to benchmark reference quantities have been established for the beam …

## Turbulent Flow Over a Backwards Facing Step (OpenFOAM)

## Turbulent Flow Over a Backwards Facing Step (OpenFOAM)

Flow over backwards facing steps are classic computational fluid dynamics test problems, and are often used for validation of simulation codes. This test problem consists of studying how the flow field reacts to a sudden expansion in a channel. The expansion will cause a break in the flow and a recirculation or …

## Natural Convection in a Square Cavity

## Natural Convection in a Square Cavity

This multiphysics model illustrates natural convection effects in a unit square domain using the Boussinesq approximation. The model involves a Navier-Stokes equations physics mode, representing the fluid flow with solid wall or no-slip boundary conditions everywhere. In addition a heat transfer physics mode is added …
