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 ... -
Numerical simulations of hydrogen flames in reheat gas turbine combustor: effect of pressure scaling and fuel blending
With a goal toward a net-zero energy supply, hydrogen, hydrogen-enriched natural gas, and biofuels, which reduce the carbon footprint, are actively being considered for firing stationary gas turbine engines. In this regard, ... -
Numerical Simulations Of Two-Phase Reacting Flow In A Cavity Combustor
(2013-05-28)In the present work, two phase reacting flow in a single cavity Trapped Vortex Combustor (TVC) is studied at atmospheric conditions. KIVA-3V, numerical program for simulating three dimensional compressible reacting flows ... -
Numerical Simulations Of Void Growth In Ductile Single Crystals
(2010-09-03)The failure mechanism in ductile materials involves void nucleation, their growth and subsequent coalescence to form the fracture surface. The voids are generated due to fracture or debonding of second phase particles or ... -
Numerical Simulations on the Indentation Behaviour of Shape Memory Alloys
Shape Memory Alloys (SMAs) are increasingly being used as micro actuators, sensors, as self expanding cardiovascular stents and in MEMs based devices because of their ability to recover large values of imposed strain. ... -
Numerical solution of non-classical beam and plate theories using di erential quadrature method
For effcient design of the nano/micro scale structural systems, detailed analysis and through understanding of size-dependent mechanical behaviour at nano/micro scale is very critical. Various approaches have been used ... -
Numerical Studies of Axially Symmetric Ion Trap Mass Analysers
(2018-05-29)In this thesis we have focussed on two types of axially symmetric ion trap mass analysers viz., the quadrupole ion trap mass analyser and the toroidal ion trap mass analyser. We have undertaken three numerical studies in ... -

This thesis presents a numerical study of some laminar compressible boundary-layer flows with heat and mass transfer. It consists of five chapters: the first is an introductory one, the remaining four are concerned with ... -
Numerical Studies of Problems in Turbulence : 1) Fluid Films with Polymer Additives; 2) Fluid Films with Inertial and Elliptical Particles; 3) Scaled Vorticity Moments in Three- and Two-dimensional Turbulence
(2017-11-30)In this thesis we study a variety of problems in fluid turbulence, principally in two dimensions. A summary of the main results of our studies is given below; we indicate the Chapters in which we present these. In Chapter ... -
Numerical studies of rotating laminar boundary-layer flows
This thesis presents numerical studies on certain problems in steady and unsteady laminar boundary?layer flows involving rotation of either the fluid or the body. It consists of four chapters: the first is introductory, ... -
Numerical studies of shock oscillations and MRI turbulence in accretion
In this thesis, we study two different aspects of accretion flows- (i) quasi-periodic oscillations (QPOs) seen in the light curves of X-ray binaries as a possible consequence of shock oscillations, (ii) global 3D ideal ... -
Numerical Studies Of Slow Dynamics And Glass Transition In Model Liquids
(2009-12-16)An increase in the co-operativity in the motion of particles and a growth of a suitably defined dynamical correlation length seem to be generic features exhibited by all liquids upon supercooling. These features have been ... -
