A variational interface-preserving and conservative phase-field method for the surface tension effect in two-phase flows
Xiaoyu Mao, Vaibhav Joshi, Rajeev Jaiman
We present a finite element based variational interface-preserving and conservative phase-field formulation for the modeling of incompressible two-phase flows with surface tension…
Transverse flow-induced vibrations of a sphere in the proximity of a free surface: A numerical study
Amir Chizfahm, Vaibhav Joshi, Rajeev Jaiman
We present a numerical study on the transverse flow-induced vibration (FIV) of an elastically mounted sphere in the vicinity of a free surface at subcritical Reynolds numbers. To b…
A variational flexible multibody formulation for partitioned fluid-structure interaction: Application to bat-inspired drones and unmanned air-vehicles
Vaibhav Joshi, Rajeev K. Jaiman, Carl Ollivier-Gooch
We present a three-dimensional (3D) partitioned aeroelastic formulation for a flexible multibody system interacting with incompressible turbulent fluid flow. While the incompressib…
A hybrid variational Allen-Cahn/ALE scheme for the coupled analysis of two-phase fluid-structure interaction
Vaibhav Joshi, Rajeev K. Jaiman
We present a novel partitioned iterative formulation for modeling of fluid-structure interaction in two-phase flows. The variational formulation consists of a stable and robust int…
