Aug 2022 - Present

Project Scientist

IIT Kanpur

Studied the dynamics of flow of SARS-Cov-2 virus through respiratory droplets in a conference room during meetings.
As recognized by WHO, physical meetings are a potential vector for spread of the respiratory virus. Using fluid dynamics studies we numerically studied meeting scenarios in closed conference rooms. The research is published in Physics of Fluids.

Integrated radiation modules in NICAM - a high resolution weather forecasting software.
The Non-hydrostatic Icosahedral Atmospheric Model (NICAM) software is written in modern Fortran language, designed to run on high-performance computing clusters, using MPI and OpenACC. NICAM is a global forecasting system with a capability of sub-kilometer resolution.

Doctorate of Philosophy (PhD)
PhD Thesis: Development of a Novel Accurate VOF Method for Incompressible Two-phase Fluid Flow.

The thesis makes two important contributions to the field of multiphase flow analysis. The first contribution is the Harten-Lax-van Leer contact preserving Riemann solver for two-phase flows. The second contribution is the development of an extremely accurate and efficient interface reconstruction technique which works with a Riemann solver. The two contributions together produce very efficient and accurate solutions to problems involving two-phase flows.

  • When I am not doing research, I involve myself in many outdoor activities such as inline-skating, swimming and hiking.
  • Yoga, Pranayama and Meditation are my go to activities to rejuvenate myself and when I am in need of an inspiration or new ideas.
  • When confined to indoors, I love reading books for personal development and spiritual growth.
  • I spend a lot of my free time in developing open source resources available at my github page. I simply love programming tools and sharing them with others. GitHub is such a wonderful medium for that!
  • Currently, I am working on solving the interesting problems from the book Compressible Fluid Flow by Patrick H. Oosthuizen and William E. Carscallen, which are published here. Currently I am giving out the solutions only to students and teachers after filling a form at the link.
  • I have also started writing blogs. I will be writing about CFD tools, Compressible fluid flows and Numerical methods.
