Solution Recording and Playback: Vortex Shedding

This tutorial demonstrates how to use the solution recording and playback module for capturing the results of transient phenomena.

The particular scenario being modeled is that of incompressible air flowing over a cylinder with diameter D = 0.01 m. Under the correct conditions, vortices are formed and shed from the cylinder in a regular pattern. The free-stream velocity is 0.15 m/s and the flow is laminar with a Reynolds number (Re) of 75. The predicted Strouhal number and shedding frequency can be determined from a graph of measured lift forces and compared to results obtained by Daily et al.[413].

A 2D volume mesh of a simple cylinder in a fluid domain is provided for this tutorial, the dimensions of which are shown below.
