Discrete Element Method (DEM) simulation for structure of fractal aggregates and their hydrodynamic properties

A simulation project for estimating mobility of nano-particle aggregates. These are looslely packed, non-spherical fluffy structures formed during processes such as synthesis of catalyst particles, transport of nano-particle slurries, transport of pollutants, etc..  read more »

Jamming of Colloidal Suspensions

Pressure driven flows of colloidal suspensions through small openings often seal the constriction. Any further flow of fluid is blocked. Time taken for jamming and effectiveness of the seal depend on particle size, concentration, particle elastic modulus, etc.. The project will include experiments, modeling and/or simulations to understand this phenomenon.

Simulaition study of Enhance Oil Recovery

In the secondary and tertiary phase of oil recovery, the crude oil in direct contact with mineral surface needs to be displaced using external medium, mostly water. The mechanism of replacement is governed by the structural and energetic behaviour of interfacial water versus hydrocarbon oil at the mineral surface. This project is aimed at understanding the interfacial behaviour of crude oil-water at mineral interface. The obtained understanding will be used to enhance the oil recovery.

Structure and Dynamics of Interfacial Water

Water is one of the most abundant, ubiquitous and essential material to sustain all biological life on earth. Most of the water exists in large bodies (bulk quantities) in the ocean, river and lakes. However, in many industrial and scientifically relevant conditions, water is associated with other surfaces. Understanding its structure and dynamics at molecular length-scale is useful in catalysis,corrosion, adsorption and atmospheric sciences.

Understanding the Shear-thickening phenomenon

Shear-thickening refers to the phenomenon where the viscosity of the liquid increases with shear. A familiar example is that of corn-starch in water, wherein the liquid can thicken to such an extent that it can even support the weight of person. While shear-thickening has been observed in some fluids and can lead to serious processing difficulties, the exact mechanism responsible for the thickening is not clear. The proposed project will investigate the role of interparticle forces and hydrodynamic interactions to understand this phenomenon.  read more »

Modeling wetting behaviour of nanoparticles

Please contact me if you are interested in this area. The project is compulational base and would involve lots of programming and running simulation softwares. The skills required are; a) good basics in transport phenomena, b) basic (primariy level of) understanding in interfacial science and c) good programming skills.

Design of Materials using Arrested Microemulsions

The project will explore design of materials using nanostructured glasses. Presently our lab is preparing and charactertising these glass-like materials. An incoming student can take the project towards design of structured nanocomposites.  Experimentation will be based on tools required to characterize the rheology, microstructure and the phase diagrams. Interested students can approach me and also talk to the DD student presently working with these materials.
