The Department of Mechanical, Materials, and Aerospace Engineering presents the Midwest Mechanics Seminar Series featuring guest speaker Bharath Ganapathisubramani, professor of experimental fluid mechanics in the Department of Aeronautics and Astronautics at the University of Southampton, who will present “Vortex Dominated Flows: Can’t Live with Them…Can’t Live Without Them…” This event is open to the public and will take place on Wednesday, December 3, from 12:45–1:45 p.m. Please note the new location for this seminar, which will be in room 104 of the Stuart Building.

Abstract

Vortex-dominated flows are in abundance in engineering applications and natural environment. Vortical structures influence not only the flow field but also have major implications on forces and moments experienced by objects as well as noise generated by them. If we are able to predict/infer the presence and characteristics of these vortices, then we can harness their potential to our benefit. In this talk, I will present results from work carried out in my group across different projects. We will focus on at least two case studies, one where the presence of vortices is detrimental to the aerodynamic performance while another where the influence of the vortices can be harnessed to improve efficiency. These examples come from varied application areas including flow over stalled airfoils, flow past bluff bodies to multiple flapping foils.

Biography

Bharath Ganapathisubramani is a professor of experimental fluid mechanics in the Department of Aeronautics and Astronautics at the University of Southampton. He completed his master’s and Ph.D. in aerospace engineering at the University of Minnesota and an undergraduate degree in naval architecture and ocean engineering at the Indian Institute of Technology-Madras. He was an assistant professor at Imperial College London (2007–2010) and moved to Southampton, where he was a senior lecturer (2010–2012) and then as professor. He currently serves as an associate editor for Experiments in Fluids and Flow. He is a Fellow of Royal Aeronautical Society and the American Physical Society as well as an Associate Fellow of AIAA.
