Supersonic Flow Past a Wedge

Supersonic Flow Past a Wedge

This verification test case studies steady inviscid compressible flow past a wedge at an incident angle of 15 degrees. As the supersonic flow (Ma = 2.5) hits the wedge a sharp oblique shock wave is formed, resulting in a reduced downstream flow velocity. The simulation uses the inviscid compressible Euler equations to …

Non-Newtonian Flow in an Extrusion Die

This example models flow of a polymer through an extrusion die with two outlets. This type of flow can for example be found in manufacturing processes of plastic parts. The polymer is assumed to be non-Newtonian, and can be modeled with a shear thinning Bird-Carreau viscosity model. The die is also assumed to be …

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

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

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

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 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 …
