Summary of An Introduction to RANS Turbulence Modelling in OpenFOAM

00:00:00 - 00:10:00

This video demonstrates how to modify an existing turbulence model to be more suitable for use in OpenFOAM. The presenter describes how they compiled their own turbulence modelling library and then demonstrates how it was used to produce two velocity profiles across a flat plate.

• 00:00:00 The turbulence modeling on OpenFOAM allows for the simplification of the flow, and it's often used in conjunction with the three-dimensional Marios equations which have been solved perfectly with our computational power. In order to do this, the turbulence model must be able to approximate the mean quantity. There are many viscosity models available on the OpenFOAM platform, and the two most commonly used are the SST K Omega and the SSD model.
• 00:05:00 OpenFOAM is a powerful software program that allows users to model fluids and turbulence. This video introduces the basics of turbulence modeling in OpenFOAM, and shows how to modify an existing turbulence model to be more suitable for use in OpenFOAM.
• 00:10:00 The presenter describes how they compiled their own turbulence modelling library and then demonstrates how it was used to produce two velocity profiles across a flat plate.
