Effect of combined heaving and pitching on propulsion of single and tandem flapping foils
Amit S. Hegde, Pardha S. Gurugubelli, Vaibhav Joshi
In this study, we present two and three-dimensional numerical investigation to understand the combined effects of the non-dimensional heave amplitude varying from 0 to 1 and the pi…
Propulsive performance of morphing and heaving foil
Pragalbh Dev Singh, Ishan Neogi, Vardhan Niral Shah +1
Biological locomotion, observed in the flexible wings of birds and insects, bodies and fins of aquatic mammals and fishes, consists of their ability to morph the wings/fins. The mo…
Non-dimensional parameters for the flapping dynamics of multilayered plates
Esha Jain, Aditya Karthik Saravanakumar, V. Joshi +1
The coupled flow-induced flapping dynamics of flexible plates in uniform axial flows are governed by three non-dimensional numbers, namely: Reynolds number , mass-ratio $(m^*…
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…
