Our core research is multiphase flows and phase change: condensation, frosting, boiling, and the dynamics of droplets, bubbles, and particles. We connect fundamental interfacial physics with engineered surfaces, microfluidics, and thermal management across scales.

Associate Professor, Department of Mechanical Engineering, IIT Madras
The group combines experiments, modelling, simulations, visualization, surface fabrication, thermal diagnostics, and data-driven methods to understand transport phenomena in complex fluid systems and translate them into useful technologies.
Prof. Pallab Sinha Mahapatra is also associated with the ISRO-IIT Madras Centre of Excellence for Fluid and Thermal Sciences since 2025.
