Aerobreakup of a Polymeric Droplet
Aerobreakup of a liquid droplet refers to the process of breaking the droplet into smaller fragments by subjecting it to a sufficiently high-speed stream of gas (generally air). This process lies at the core of various ... -
Coalescence of Polymeric Droplets
Coalescence is an energy minimization phenomenon in which two equilibrium droplets undergo a transition to attain a final equilibrium state, i.e., a coalesced state. Coalescence begins with a point contact between the ... -
Contact Line Instabilities in Thin Film Flows on Curved Surfaces
Thin fluid film flows are ubiquitous in nature and many industrial applications. Such flows are characterized by having the thickness in one direction being much smaller than the characteristic length scales in the ... -
Direct Numerical Simulation of Square Vortex Flows
Atmospheric and oceanic flows are often modeled as two-dimensional due to their large planar extents (∼ 1000 km) and small vertical extent (∼ 10 km). Most phenomena in these systems are governed by the theory of two-dimensional ... -
Dynamics of Leidenfrost droplets on microtextured substrates
A liquid droplet placed on a heated substrate at temperatures significantly higher than the saturation temperature of the liquid levitates over a thin film of vapor and is termed as a Leidenfrost (LF) droplet. Leidenfrost ... -
Evaporation Driven Oscillations and Particle Agglomeration in Pure and Complex Fluid Sessile Droplets
A sessile droplet forms a fundamental building block in analyzing particle distribution and deposition in both industrial applications and lab on a chip research such as inkjet printing, surface patterning, photonic crystals, ... -
Experimental studies on Soot and Particulate reduction in Heavy Fuel Oil Combustion
Heavy fuel oil (HFO) is extensively used in industrial burners and marine engines. HFO droplet combustion gives rise to carbon particulates generated by pyrolysis, which are called cenospheres. There is a current hypothesis ... -
Insights into evaporation, atomization and precipitate formation of polymer droplets
Evaporation of polymer droplets is an active area of interest due to its applications in systems such as ink jet printing, thin films, spray combustors to name a few. Thus, understanding complex dynamics of evaporating ... -
Insights of Evaporation Dynamics of an Interacting Linear Array of Droplet System
Manipulation of an array of sessile droplets organized in an ordered structure turns out to be of immense consequence in a wide variety of applications ranging from photonics, near field imaging and inkjet printing on one ... -
Liquid bridge breakup and detachment dynamics investigated using dynamic domain multiphase flow simulations
Liquid bridges, formed between two solid surfaces in close proximity are encountered in a variety of engineering and daily life applications. The dynamics of a liquid bridge including its evolution that typically involves ... -
One-domain simulation of fluid flow and heat transfer in the conjugate porous-clear media
In this thesis, based on generalized porous flow model, we present a one-domain framework for the simulation of incompressible flow in superposed clear and porous media. The continuous change in the characteristics of the ... -
Particle-laden Rayleigh-Benard convection
Particle-laden flows are ubiquitous in nature and industries. For example, water droplets in clouds, fine dust particles in strong winds leading to dusty storms, dunes, ejection of solid particles and ash during volcanic ... -
Rotary atomization of non-Newtonian liquids for Spray drying applications
Food wastage poses a significant threat to the nation’s food supply and safety due to inadequate storage infrastructure and logistics facilities. This study explores the potential of spray drying as a viable solution to ... -
Secondary Atomization of a Droplet in Diverse Interaction Settings
Secondary atomisation refers to the process by which liquid droplets, which are already in a dispersed state, are further atomised down into smaller droplets. This process occurs after primary atomisation, which is the ... -
Spatio-temporal Dynamics in Droplet Combustion Under Diverse Flow Conditions
Spray combustion of liquid fuels is one of the most ubiquitous modes of combustion used in a wide range of applications ranging from IC engines for transportation to Gas turbines in propulsion systems, owing to the high ... -
Stability of wall-bounded compressible shear flows
In this work, the linear stability of compressible shear flows in channels and pipes are studied. A steady fully-developed laminar flow of an ideal gas, driven in a channel and a pipe by a constant body acceleration, is ... -
Torque transport, mean velocity profiles and turbulent statistics of a wide-gap Taylor Couette flow
Wall-bounded turbulent flows that possess finite curvature of the mean flow streamlines are known to be starkly different from their plane counterparts. One of the primary distinguishing features of such flows is the ... -
Vapor Mediated Interaction in Droplets
Controlling internal flow in evaporating sessile droplets is desirable across applications ranging from lab-on-chip medical diagnostics, DNA profiling to surface patterning. Diffusion-limited evaporation in droplets exhibits ...
