Welcome to the Computational Physics of Flows and Materials lab at IIT Delhi headed by Dr. Prateek Gupta. We combine computational and theoretical techniques to investigate the mechanics of fluid flows and materials across scales. At microscales, we develop advanced techniques for statistical coarse-graining of the first principles-based calculations. At mesoscales, we use these coarse-graining techniques to bridge microscales and continuum scales using kinetic models. At macroscales, we use the averaged kinetic models to understand various fundamental phenomena such as thermal transport, mass transport, energy exchange among scales, nonlinear wave propagation, and applicative phenomena such as flow turbulence, nonlinear waves, flow stability, compliant materials, and many more. We leverage high-performance computing techniques to scale these models and understandings to aid technological development including high-speed vehicles, renewable energy harvesting devices, and batteries. The central focus of our lab is to scale up the first-principles-based calculations to macroscales mechanics of fluids and solids using high-performance computing and statistical approximations in collaboration with other research groups in computer science, mechanical engineering, and material science departments. Besides research in fluid mechanics, molecular mechanics, and solid mechanics, we also provide support to industry in wide-ranging issues related to fluid mechanics, thermal transport, and mass transport across scales.
