What is a Centrifugal Pump ?
A Centrifugal pump is a rotoynamic pump which transfer liquids from suction to discharge by converting kinetic energy of liquids into potential energy.

Working Principle of Centrifugal pump

The working principle of Centrifugal pump is converting kinetic energy of liquids into potential energy to transfer liquids by imparting energy to the liquid by means of a centrifugal force developed by the rotation of an impeller that has several...

Create a hollow cylinder. Thanks.

This is a pretty specific issue which relates to my experience working on wall functions and the Spalart-Allmaras model, but might be useful to others or, more importantly, the users of their code.

If you followed my previous posts here, you know I developed a wall function formulation based on the Musker wall function which, thanks to a math trick, is integrable also for arbitrary Pr/Pr_t (Sc/Sc_t) numbers and also for some forms of non equilibrium terms.

One of the...

I am sharing a few tips and tricks for better OpenFOAM simulations. These are not any new tips I discovered. These are just some which I felt most useful based on my experience.

1. Mesh is the most important aspect - I have spent countless hours fixing issues in other places while the real issue was with my mesh. As a thumb rule, make sure the mesh has: no non-orthogonality issues, low aspect ratio cells, no refinement zones in the region with high gradients

2. Always start...
