Vortex topology in the lee of a 6:1 prolate spheroid
Marc Plasseraud, Krishnan Mahesh
A large scale parametric study of the flow over the prolate spheroid is presented to understand the effect of Reynolds number and angle of attack on the separation, the wake format…

Monolithic framework to simulate fluid-structure interaction problems using geometric volume-of-fluid method
Soham Prajapati, Ali Fakhreddine, Krishnan Mahesh
We develop a three-dimensional Eulerian framework to simulate fluid-structure interaction (FSI) problems on a fixed Cartesian grid using the geometric volume-of-fluid (VOF) method.…

Definition of vortex boundary using stagnation pressure
Marc Plasseraud, Krishnan Mahesh
A novel method is proposed to identify vortex boundary and center of rotation based on tubular surfaces of constant stagnation pressure and minimum of the stagnation pressure gradi…
