About
Presently, I am employed as a Postdoctoral Researcher at the Flow Physics and Computation Lab at Johns Hopkins University, under the supervision of Prof. Rajat Mittal. I have worked extensively on development of numerical algorithms for solving high dimensional partial differential equations (PDE) on massively parallel CPU/GPU architectures (C++/CUDA/MPI). Generally, these PDEs are used to simulate physics problems involving multiphase-flows and fluid-structure interaction (e.g. nucleate boiling, wave powered propulsion systems).
My current research focuses on elucidating the flow physics of wave-induced flapping foil propulsion systems through numerical simulations on parallel CPU architectures. Notably, I have been instrumental in the development of the VOF solver within this lab and for coupling it with the immersed boundary solver to integrate fluid-structure interaction and multiphase flows. Additionally, I am actively engaged in the application of Deep Learning techniques to augment my research.
During my doctoral tenure, I conducted research under the supervision of Prof. Atul Sharma and Prof. Amitabh Bhattacharya at the Indian Institute of Technology (IIT), Bombay. My doctoral work centered on the computational advancement (using C++/CUDA/MPI) of Multi-Fluid Structure Interaction for investigating nucleate boiling under the influence of externally actuated surfaces. To this end, I implemented a hybrid approach combining level set and immersed boundary methods. Furthermore, I developed novel technique to apply Deep Reinforcement Learning to active flow control problems (5.5x faster) and successfully applied the technique to regulate the oscillations of the boiling surface, with the primary goal of enhancing heat transfer efficiency.
