Saurabh S. Sawant  (He/Him)

Hello, I am Saurabh, a postdoctoral scholar in the Center for Computational Sciences and Engineering (CCSE) in the Applied Math & Computational Research Division at the Lawrence Berkeley National Lab (LBNL) since January 2022.

My PhD research background is in kinetic modeling and instability analysis of complex hypersonic high-temperature nonequilibrium flows. I have worked primarily on the Direct Simulation Monte Carlo (DSMC) method with a focus on developing high performance computing algorithms to model large-scale kinetic systems (e.g. model 3-D Mach 7 flow over a double-wedge geometry using 60 and 4.5 billion comutational particles and cells, respectively).

My PhD work involved understanding theoretical aspects of shocks such as the nature of molecular fluctuations in their internal structure, their intrinsic stability against small-amplitude harmonic perturbations, and their synchronous coupling with laminar separation bubble in the shock-wave/boundary-layer interactions.

At LBNL, I have shifted gears and am working in team of computational scientists developing applications of computational electromagnetism to microelectronics and quantum chip devices in collaboration with theorists and experimentalists. In the near term, I will be developing DSMC algorithms to characterize electron-hole transport in nano-CMOS devices.

2022 Highlights

March 2022: Our work entitled, "on the synchronisation of three-dimensional shock layer and laminar separation bubble instabilities in hypersonic flow over a double wedge", is accepted for publication in the Journal of Fluid Mechanics.

Select 2021 Highlights

Sept 2021: Our work on the Analytical Predictions of Low-frequency Fluctuations in a Shock-Layer is published in the journal of Theoretical and Computation Fluid Dynamics and a related work, A Kinetic Approach to Studying Low-frequency Molecular Fluctuations in a One-Dimensional Shock, is published in the Physics of Fluids journal as editor's pick.

The beautiful background is the Boneyard Creek passing through the Engineering Quad at UIUC. Favourite place of geese on campus.
