An Aeroelastic Solver Integrating Reformulated-Vortex-Particle and Finite-Element Methods across Non-Conforming Interfaces
Neeraj Balachandar, A. Padmaprabhan, Vishnu R. Unni
We present (Variable Fidelity Unsteady Flow-FEniCS Exchange Interface), a modular aeroelastic solver for modeling two-way fluid-structure interaction (FSI) of f…
Nonlinear Model Predictive Control via Sequential Convex Programming for Drone-to-Drone Docking
Neeraj Balachandar, Shriram Hari, Vishnu R. Unni
Autonomous mid-air docking of multi-rotor vehicles under disturbance-driven target motion poses a constrained non-linear trajectory optimization challenge. This work formulates the…
Control of growth of local heat release rate fluctuations to suppress thermoacoustic instability
M. Raghunathan, N. B. George, V. R Unni +3
This experimental study investigates the dynamical transition from stable operation to thermoacoustic instability in a turbulent bluff-body stabilized dump combustor. We conduct ex…
Detection of Dynamical Regime Transitions with Lacunarity as a Multiscale Recurrence Quantification Measure
Tobias Braun, Vishnu R. Unni, R. I. Sujith +2
We propose lacunarity as a novel recurrence quantification measure and illustrate its efficacy to detect dynamical regime transitions which are exhibited by many complex real-world…
Synchronization framework for modeling transition to thermoacoustic instability in laminar combustors
Yue Weng, Vishnu R. Unni, R. I. Sujith +1
We, herein, present a new model based on the framework of synchronization to describe a thermoacoustic system and capture the multiple bifurcations that such a system undergoes. In…
Modeling ambient temperature and relative humidity sensitivity of respiratory droplets and their role in Covid-19 outbreaks
Swetaprovo Chaudhuri, Saptarshi Basu, Prasenjit Kabi +2
One of the many unresolved questions that revolves around the Covid-19 pandemic is whether local outbreaks can depend on ambient conditions like temperature and relative humidity.…
