Event Name (Full/Detailed): 

The Indian Institute of Technology Bombay is organizing an Institute lecture on Monday, February 13, 2023. The details of the lecture are given below:

Title: "Flow Physics and Computation at the Intersection of Mechanics and Bioengineering"

Speaker: Professor Rajat Mittal, Professor of Mechanical Engineering and Professor of Medicine, Johns Hopkins University, Baltimore, USA


About the speaker: Rajat Mittal is a professor of mechanical engineering and professor of medicine at Johns Hopkins University, Baltimore, USA. He has done pioneering work in the development of computational methods for fluid dynamics, in particular, immersed boundary methods, and applications of these methods in several interdisciplinary fields. Examples include, biomedical fluid dynamics (cardiovascular flows), biological and bioinspired locomotion (swimming and flying), bioacoustics, active flow control, fluid-structure interaction, and high-performance computing. He is an elected as a fellow of the American Physical Society and American Society of Mechanical Engineers and a recipient of several notable awards such as ASME Freeman Scholar in 2021. He serves on editorial board on top journal in these fields such as Journal of Computational Physics and Journal of Experimental Biology. http://engineering.jhu.edu/f

Abstract: The unceasing growth in computational power and the development of new software tools and numerical algorithms is opening up exciting areas of research, discovery & translation in mechanics and biomedical engineering. Consider the mammalian heart, which has been sculpted by millions of years of evolution into a flow pump par excellence. During the typical lifetime of a human, the heart will beat over three billion times and pump enough blood to fill over sixty Olympic-sized swimming pools. Each of these billions of cardiac cycles is itself a manifestation of a complex and elegant interplay between several distinct physical domains including electrophysiology, muscle mechanics, hemodynamics, flow-induced valves dynamics, acoustics, and biochemistry. Computational models provide the ability to explore such multi-physics problems with unprecedented fidelity and precision. In my talk, I will describe several projects that demonstrate the application of powerful computational tools to problems ranging from clot formation, and heart murmur detection, to anomalous function of implanted heart valves. Application of these tools to problems in other arenas of mechanics such as bio-locomotion, fluid-structure interaction, and energy harvesting will also be discussed.
