Transport of Particles, Drops, and Small Organisms in
Density Stratified Fluids
West Lafayette, IN
Many aquatic environments are characterized by regions where water density varies over depth, often due to temperature or salinity gradients. These ‘pycnoclines’ are associated with intense biological activity and can affect carbon fluxes by slowing the descent of particles. Despite this, the fundamental fluid dynamics of settling and swimming in a stratified fluid have remained largely unexplored. I take first strides into this area by rationalizing the effects of stratification by conducting a broad, in-depth investigation on the fundamental hydrodynamics of small organisms, settling particles, and rising drops. These results demonstrate an unexpected effect of buoyancy, potentially affecting a broad range of abundant processes at pycnoclines in oceans and lakes.
Arezoo Ardekani is currently an assistant professor at the Purdue University. Prior to joining Purdue, she was an O’Hara Assistant Professor at the University of Notre Dame and a Shapiro Postdoctoral Fellow at the Massachusetts Institute of Technology. In summer 2015, she was a visiting professor at the Institut de Mécanique des Fluides de Toulouse. She graduated from University of California Irvine with her Ph.D. in 2009. She received the Society of Women Engineers and Amelia Earhart awards in 2007, Schlumberger Foundation faculty for the future grant in 2009, and NSF CAREER award in 2012.
Prof. Ardekani was awarded the Presidential Early Career Award for Scientists and Engineers (PECASE) in 2016. She has presented 50 invited lectures in conferences, universities, and industries worldwide. She is a member of the board of editors of the European Journal of Computational Mechanics and Scientific Reports. Her expertise is in fluid mechanics, biological and environmental flows.
