Preferential sampling enabled by particle finite size and anisotropic shape
Helena E. Schreder, Kartik Krishna, Steven L. Brunton +1
Anisotropic, finite-sized particles, common in environmental and industrial flows, exhibit complex dynamics distinct from those of small, spherical particles. Their shape introduce…
Leveraging three-dimensionality for navigation in bluff-body wakes
Vedasri Godavarthi, Kartik Krishna, Steven L. Brunton +1
Biological flyers and swimmers navigate in unsteady wake flows using limited sensory abilities and actuation energies. Understanding how vortical structures can be leveraged for en…
Control of Vortex Dynamics using Invariants
Kartik Krishna, Aditya G. Nair, Anand Krishnan +2
Vortex-dominated flows are ubiquitous in engineering, and the ability to efficiently manipulate the dynamics of these vortices has broad applications, from wake shaping to mixing e…
Finite Time Lyapunov Exponent Analysis of Model Predictive Control and Reinforcement Learning
Kartik Krishna, Steven L. Brunton, Zhuoyuan Song
Finite-time Lyapunov exponents (FTLEs) provide a powerful approach to compute time-varying analogs of invariant manifolds in unsteady fluid flow fields. These manifolds are useful…
Finite-Horizon, Energy-Optimal Trajectories in Unsteady Flows
Kartik Krishna, Zhuoyuan Song, Steven L. Brunton
Intelligent mobile sensors, such as uninhabited aerial or underwater vehicles, are becoming prevalent in environmental sensing and monitoring applications. These active sensing pla…
