Force moment partitioning and scaling analysis of vortices shed by a 2D pitching wing in quiescent fluid
Yuanhang Zhu, Howon Lee, Sushrut Kumar +3
We experimentally study the dynamics and strength of vortices shed from a NACA 0012 wing undergoing sinusoidal pitching in quiescent water. We characterize the temporal evolution o…
Contribution of spanwise and cross-span vortices to the lift generation of low-aspect-ratio wings: Insights from force partitioning
Karthik Menon, Sushrut Kumar, Rajat Mittal
This study reports on the vortex-induced lift production mechanisms in low Reynolds number flows over low aspect-ratio rectangular wings. We use a rigorous force partitioning metho…
Significance of the strain-dominated region around a vortex on induced aerodynamic loads
Karthik Menon, Rajat Mittal
The ability of vortices to induce aerodynamic loads on proximal surfaces plays a significant role in a wide variety of flows. However, most studies of vortex-induced effects primar…
Quantitative analysis of the kinematics and induced aerodynamic loading of individual vortices in vortex-dominated flows: a computation and data-driven approach
Karthik Menon, Rajat Mittal
A physics-based data-driven computational framework for the quantitative analysis of vortex kinematics and vortex-induced loads in vortex-dominated problems is presented. Such flow…
On the initiation and sustenance of flow-induced vibration of cylinders: insights from force partitioning
Karthik Menon, Rajat Mittal
The focus of this work is to dissect the physical mechanisms that drive and sustain flow-induced, transverse vibrations of cylinders. The influence of different mechanisms is quant…
Aeroelastic response of an airfoil to gusts: Prediction and control strategies from computed energy maps
Karthik Menon, Rajat Mittal
A method to predict the aeroelastic pitch response of an airfoil to gusts is presented. The prediction is based on energy maps generated by high-fidelity fluid dynamic simulations…
Dynamic mode decomposition based analysis of flow over a sinusoidally pitching airfoil
Karthik Menon, Rajat Mittal
Dynamic mode decomposition (DMD) has proven to be a valuable tool for the analysis of complex flow-fields but the application of this technique to flows with moving boundaries is n…
Phase Separation and Coexistence of Hydrodynamically Interacting Microswimmers
Johannes Blaschke, Maurice Maurer, Karthik Menon +2
A striking feature of the collective behavior of spherical microswimmers is that for sufficiently strong self-propulsion they phase-separate into a dense cluster coexisting with a…
Attraction-induced jamming in the flow of foam through a channel
Karthik Menon, Rama Govindarajan, Shubha Tewari
We study the flow of a pressure-driven foam through a straight channel using numerical simulations, and examine the effects of a tuneable attractive potential between bubbles. This…
