Regime identification for stratified wakes from limited measurements: a library-based sparse regression formulation
Vamsi Krishna Chinta, Chan-Ye Ohh, Geoffrey Spedding +1
Bluff body wakes in stratified fluids are known to exhibit a rich range of dynamic behavior that can be categorized into different regimes based on Reynolds number () and Froud…
Simulation-Based Analysis of COVID-19 Spread Through Classroom Transmission on a University Campus
Arvin Hekmati, Mitul Luhar, Bhaskar Krishnamachari +1
Airborne transmission is now believed to be the primary way that COVID-19 spreads. We study the airborne transmission risk associated with holding in-person classes on university c…
The Effect of Super-spreader Events in Epidemics
Harisankar Ramaswamy, Assad A Oberai, Mitul Luhar +1
The spread of infectious epidemics is often accelerated by super-spreader events. Understanding their effect is important, particularly in the context of standard epidemiological m…
Model-based multi-sensor fusion for reconstructing wall-bounded turbulence
Mengying Wang, C. Vamsi Krishna, Mitul Luhar +1
Wall-bounded turbulent flows can be challenging to measure within experiments due to the breadth of spatial and temporal scales inherent in such flows. Instrumentation capable of o…
Locomotion and Control of a Friction-Driven Tripedal Robot
Mark Hermes, Taylor McLaughlin, Mitul Luhar +1
This letter considers control of a radially symmetric tripedal friction-driven robot. The robot features 3 servo motors mounted on a 3-D printed chassis 7 cm from the center of mas…
Resolvent-based predictions for turbulent flow over anisotropic permeable substrates
Andrew Chavarin, Garazi Gomez-de-Segura, Ricardo Garcia-Mayoral +1
Recent simulations indicate that streamwise-preferential porous materials have the potential to reduce drag in wall-bounded turbulent flows(Gomez-de-Segura & Garcia-Mayoral 2019).…
