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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
