Particles@IITB

Our group studies the dynamics of anisotropic particles suspended in fluid flows — a key problem in understanding the microphysics of complex suspensions. Such systems are found across nature and industry, ranging from blood and pulp suspensions all the way to clouds that play a crucial role in the earth-atmosphere radiation budget.

We use theoretical models and numerical simulations to investigate how particle orientation and motion influence rheology, viscosity, and optical properties. Our research lies at the intersection of fluid mechanics, applied mathematics, and computational physics, aiming to bridge microscopic particle behavior with macroscopic flow phenomena.

Research Themes

• Hydrodynamics of droplets in a channel flow

• Motion of anisotropic particles in turbulence

• Beyond perturbation: Homotopy Analysis methods in fluid dynamics

Approach and Philosophy

We believe that impactful engineering research arises from rigorous fundamentals connected to technological relevance.
Our approach emphasizes:

• Integration of analytical, computational, and experimental insights.
• Open, reproducible research practices.
• Collaboration across disciplines — spanning applied mathematics and fluid dynamics

Our long-term vision is to translate fundamental fluids into tangible technologies that address challenges in energy, environment, and health.
