Vortex shedding behind a square at Re = 50000The purpose of this post is to illustrate a vortex shedding application in the case of a square obstacle. The OpenFOAM® solver used is pimpleFoam solver (based on the PIMPLE pressure / velocity coupling algorithm). The mesh is generated with blockMesh and the results are post-processed with…
How to add a passive scalar to your OpenFOAM® simulationsThe purpose of this post is to show how to add a passive scalar to your simulations without modifying a given solver. This feature is, for example, very useful when trying to track the concentration of inert species. The tutorial Cavity The Cavity tutorial is part…
Turbulent flow in a 90° bend The flows in pipe (straight, bent …) are involved in many industrial processes such as heat exchangers and cooling systems, piping etc. Experimentally this type of flow was largely studied in the 1980s in rectangular pipe (pressure loss measurements, velocity fields with Pitot tube …). In 1998 Sudo et…
