Lattice Boltzmann methodology for unconfined flows
Vemu Sahiti, PS Gurugubelli, VK Surasani
Numerical analysis of unconfined flow over an obstacle has always been challenging in computational fluid dynamics due to the truncation of the computational domain while replicati…
Performance Evaluation of a Fan-Array Wind Tunnel for Advanced Aerodynamic Studies
Kalyani Panigrahi, Rohan Bhattacharya, Sabareesh G. R. +1
Wind tunnel's consisting an array of computer controlled/programmable fans have evolved over the last three decades for simulating the atmospheric turbulence to study the aerodynam…
Self-Induced Flapping Dynamics of a Horizontal Flexible sheet in a Uniform Flow
Kalyani Panigrahi, Pardha S Gurugubelli, Sabareesh G R
The case of a conventional flexible sheet in a uniform flow has been of interest in understanding the underlying physics of passive coupled dynamics between a flexible structure an…
Two-Dimensional Numerical Analysis on Vortex-Induced Vibrations of an Elastically Mounted Circular Cylinder Placed Very Close to a Wall
V Brahmini Priya P, Aditya Karthik, Vedanth N K +2
Two-dimensional numerical simulations have been performed to understand the effect of wall proximity on the vortex-induced vibrations (VIV) of an elastically mounted circular cylin…
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…
A 3D Numerical Investigation into the Effect of Rounded Corner Radii on the Wind Loading of a Square Cylinder Subjected to Supercritical Flow
Nivedan Vishwanath, Aditya Karthik Saravanakumar, Kush Dwivedi +3
Tall buildings are often subjected to steady and unsteady forces due to external wind flows. Measurement and mitigation of these forces becomes critical to structural design in eng…
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^*…
Numerical Study on Flapping Dynamics of a Flexible Two-Layered Plate in a Uniform Flow
Aditya Karthik S., Supradeepan K., P. S. Gurugubelli
Over the past few decades, the prospect of energy generation from an oscillating piezoelectric patch has gained attention. A typical setup of this kind would be a piezoelectric pat…
A Variational Projection Scheme for Nonmatching Surface-to-Line Coupling between 3D Flexible Multibody System and Incompressible Turbulent Flow
P S Gurugubelli, R Ghoshal, V Joshi +1
This paper is concerned with the partitioned iterative formulation to simulate the fluid-structure interaction of a nonlinear multibody system in an incompressible turbulent flow.…
On the Mechanism of Large Amplitude Flapping of Inverted Foil in a Uniform Flow
P. S. Gurugubelli, R. K. Jaiman
An elastic foil interacting with a uniform flow with its trailing edge clamped, also known as the inverted foil, exhibits a wide range of complex self-induced flapping regimes such…
