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 …
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 …
