Simulation of steady and transient flows over solid circular cylinder using ANSYS Fluent

For beginners trying to understand the basic implementation methodologies of Computational Fluid Dynamics (CFD), flow-over-a-cylinder is one of the classical problems to work with. This is because of the following:

  1. It has been widely studied in the literature, i.e. theoretically, numerically and experimentally for a variety of Reynolds number.
  2. It provides an understanding of the existence of boundary layers which was immortalised by Prandtl at the beginning of the 20th century.
  3. It has such a beautiful flow field (for the transient case) which is now formally called as the Von-Karman vortex street.

That being said, I am providing this tutorial for the people who are new to CFD and are interested in solving problems involving a Fluid-Solid Interaction (FSI). Take your time to watch it and don’t hesitate to ask me any questions.
