In collaboration with Drs. Ranganathan Gopalakrishnan and Alex Headley in the Department of Mechanical Engineering, we were recently awarded a Research Development and Partnership Pilot (RDPP) grant from the U.S. Department of Energy (DOE) starting September 1, 2022. The project is entitled “Building partnerships for development of sustainable energy systems with atmospheric measurements,” and is an Atmospheric System Research (ASR) activity within the Earth and Environmental Systems Science Division (EESSD) of the Department of Energy’s Biological and Environmental Research (BER) program.  See more here and here for more info

Ala’ is presenting his work: “Validation of Vented Gas Characteristics From Thermal Runaway of Lithium-Ion Batteries Using LIM1TR” at SHTC2022

We recently were awarded “a lot” of CPU-hours on TACC Stampede2 and Purdue Anvil towards our project “Formation Mechanisms and Modeling of Wake Meandering in Wind Farms”

The lab received an NSF award entitled: ERI: Formation Mechanisms and Modeling of Wake Meandering in Wind Farms

Apratim is presenting his work related to aerosolized respiratory droplets and turbulence at APS DFD. It’s entitled “Effects of turbulence and vortical structures on aerosolized droplets during speaking”

Our new outreach collaboration with David Horan in the University of Memphis Department of Art is highlighted in the Paper Arts Collective Newsletter.  Check out the article here.

Check our new paper on vorticity dynamics in wind turbine wakes:

Coherent vorticity dynamics and dissipation in a utility-scale wind turbine wake with uniform inflow

Check out our new paper on sub-grid characteristics of upwind-schemes for the vorticity transport equations in Physical Review Fluids. It demonstrates the behavior of a class of vorticity-velocity formulations that can be employed for large-eddy simulation of turbulent flows.

Check out the Ala’s AIAA SciTech conference paper “Reduced-order Model Predictions of Wind Turbines via Mode Decomposition and Sparse Sampling”.  The presentation is on the SciTech website in the Uncertainty Analysis Advancements for Wind Energy Applications session.  The live session is on January 19, 2021, January 19, 2021 from 2:30 PM to 3:45 PM  EST

Two 2020 APS DFD conference abstracts are submitted demonstrating preliminary work on understanding dispersion of aerosols during human respiration.

Simulations: Simulations of the Interactions of Coherent Vortical Structures and Respiratory Droplets during Expiration

Experiments: Respiratory Droplets Transport via Vortex Dynamics during Expiration

This is on-going research part of a larger project in collaboration with the faculty in the Department of Mechanical Engineering, School of Communication Sciences and Disorders, and the University of Tennessee Health Science Center.  The goals are to understand the aerosol dispersion during talking and singing.
