Who are we?

Welcome to the "Multiscale and Multiphase Fluid Dynamics" group at CORAL, IIT Kharagpur. We work with intermediate and large scale fluid dynamics and turbulence models in two major systems :

(a) Ideal Systems (length scales ~ meters) : Systems with well-defined boundary conditions and forces, and

(b) Applications to Real Systems (length scales ~ kilometers), e.g., Global Ocean Models and Climate Systems.

In particular, we are interested to understand multiphase flows, e.g., oil-water mixing and phase-separation in presence of turbulence. Based on our previous work, when a mixture of oil and water is stirred vigorously, there is a competing effect between the external stirring force, and the surface tension of oil, and this leads to many interesting effects. Such study, when applied to global ocean models, will help in the removal of marine oil-spills, as well as marine pollutants.

Our work is mostly theoretical and computational, and involves analysis and validation of results against observational satellite data. We use different tools, e.g., high-performance computing, global scale Earth System Models to study and analyse our systems.
