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 ... -
Dynamics of Bubbles and Drops in the Presence of an Electric Field
(2018-07-16)The present thesis deals with two-phase electrohydrodynamic simulations of bubble and droplet dynamics under externally applied electric fields. We used the Coupled Level-Set and Volume-of-fluid method (CLSVOF) and two ... -
Electrohydrodynamics of a Viscoelastic Drop
The behavior of a drop in electric fields is critical for diverse natural and industrial applications, including inkjet printing and electrohydrodynamic atomization. This complex phenomenon is governed by the balance of ... -
Liquid Jet in Swirling Cross Flow
Liquid jets in cross flows (JICF) have been an important part of spray research in the last few decades owing to the wide spectrum of applications ranging from agricultural sprays to aircraft gas turbine engines. However, ... -
Modeling Free Surface Flows and Fluid Structure Interactions using Smoothed Particle Hydrodynamics
(2018-06-26)Recent technological advances are based on effectively using complex multiphysics concepts. Therefore, there is an ever increasing need for accurate numerical al-gorithms of reduced complexity for solving multiphysics ... -
Multiscale Simulations in Multiphase Flows
Matter at small scales is not a continuum. Whenever we are dealing with phenomena which have disparate time and length scales, we have to rely on multiscale modelling approach in order to capture the complete physics. A ... -
Numerical Simulations of Deforming Capsules and Cells in a flow
Understanding the evolution of deforming capsules and cells in various flow configurations can assist in better diagnosis of diseases like Malaria and sickle cell anemia. Flow of deformable capsules is also useful in ... -
A Numerical Study of Droplet Dynamics in Viscoelastic Flows
(2017-10-05)The polymers are integral part of vast number of products used in day to day life due to their anomalous viscoelastic behaviour. The remarkable flow behaviour exhibited by the polymeric fluids including rod climbing, ... -
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 ... -
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 ...
