Computational Modelling of Mixing and Segregation in Crude Tanks

Crude oil stored in tanks often get segregated due to variations in their density coming from different sources, or due to the presence of water. Agitators used to mix the fluids are not efficient in achieving a uniform density. It is needed to understand the origin of this inefficiency and design the selection and placement of agitators. We will adopt a theoretical and computational methodology to study the problem and come up with designs that can be tested on the field.

Atomization: Break-up of thin liquid sheets

The process of atomization, which involves the break-up of a mass of liquid into tiny droplets, plays an important role in many industrial applications such as spray combustion, spray painting, agricultural sprays, ink jet printing, and powdered milk processing to name a few. One of the main objectives of the atomization process is to control the drop size distribution so as to achieve the desired process efficiently.  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.

Mathematical Analysis of Phoretic Motion

A suspension of colloidal particles can be subjected to various intermolecular forces that can lead to their mean motion, resulting in some intriguing macroscopic flows. This study will focus on the mathematical modelling and analysis, using semi-analytical and numerical methods to understand these flows.
