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…
