Hi, I'm Hemanth. I am a postdoctoral fellow at Johns Hopkins University working on data assimilation methods for high-speed flows. I am passionate about science, philosophy, music, and lately cats. I enjoy taking up focused challenges that allow me to dive deep into a problem and learn a wide range of new concepts along the way. Not long ago, in the midst of a war, I completed my PhD thesis at Technion; advisory of Prof. Steven Frankel and collaboration with several wonderful colleagues. On a daily basis, I go to lab, read stuff, write code, debug, and work together with colleagues. My research interests include: high-speed flows, numerical-methods, data assimilation, supersonic jet noise, and all things shock waves.
Prior to Technion, I was a master's student at the Indian Institute of Technology Madras (India) in Dr R. Sriram and group, where I performed wind tunnel experiments (Mach ≈ 3). In particular, I focused on '3-D Shock Boundary Layer Interactions'. My M.Tech thesis primarily focused on designing a suction-based control strategy to mitigate the unsteadiness in 3D-SBLIs. I also had a great opportunity of working with Dr. Nagabushana Rao in developing a high-order finite difference-based wall distance solver which drove me in to the path of CFD and numerical analysis down the line.
A Mach 1.4 Normal shock wave front passing through a localized constriction.
Although complex transient shock patterns are created as the shock passes through the constriction, the strengths of the 'transmitted' and 'reflected' shocks follow well define trends which can be accurately estimated (within 2% error) using our semi-empirical relations presented in this paper.

An unexpected 'lab meeting' on the streets of Jerusalem. Bumped into Prof. Frankel and his family while strolling at the first railway station markets.
