  In many applications the flow that past bluff bodies has frequency nature (oscillated) and it is not uniform. This kind of flow has effects on the formation of vortex shedding behind bluff bodies. In this paper the flow around a circular cylinder was numerically simulated. The effects of frequency variation ...  Read More

Numerical Simulation of Partial Cavitation over Axisymmetric Bodies: VOF Method vs. Potential Flow Theory

Mohammad Pasandidefard Fard

Volume 5, Issue 1 , March 2008, , Pages 23-33

  A computational study of partial cavitation over axisymmetric bodies is presented using two numerical methods. The first method is based on the VOF technique where transient 2D Navier-Stokes equations are solved along with an equation to track the cavity interface. Next, the steady boundary element method ...  Read More
