In this video, we'll demonstrate how to calculate the Strouhal number in ANSYS Fluent using FFT for flow over a cylinder. The Strouhal number is a dimensionless number that characterizes the unsteady flow phenomenon, such as vortex shedding. We'll walk through the steps of setting up the simulation in ANSYS Fluent, performing the FFT analysis, and extracting the Strouhal number from the results. Whether you're a beginner or an experienced user, this tutorial will help you understand and apply this important concept in computational fluid dynamics (CFD).
