WebDec 7, 2024 · The present work is focused on providing an understanding of the flow physics, mainly the vortex shedding phenomena of the cruciform shaped cylinder. The unsteady numerical flow analysis was... In fluid dynamics, vortex shedding is an oscillating flow that takes place when a fluid such as air or water flows past a bluff (as opposed to streamlined) body at certain velocities, depending on the size and shape of the body. In this flow, vortices are created at the back of the body and detach periodically from … See more The frequency at which vortex shedding takes place for an infinite cylinder is related to the Strouhal number by the following equation: $${\displaystyle \mathrm {St} ={\frac {fD}{V}}}$$ See more • Flow visualisation of the vortex shedding mechanism on circular cylinder using hydrogen bubbles illuminated by a laser sheet in a water channel.
