numerical studies of laminar compressible boundary layer flows with heat and mass transfer
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 ... -
Numerical studies of some laminar boundry layer flows using finite difference methods
This thesis presents some investigations on certain problems in laminar incompressible and compressible boundary layers using finite?difference methods. It consists of an introductory chapter and three main chapters. Each ... -
Numerical studies of some problems in mixed convection boundary layer flows
This thesis embodies the results of our investigations on some problems in mixed convection boundary-layer flows. It is divided into four chapters, the first being a general introduction to boundary-layer theory, mixed ... -
Numerical Studies of Spiral- and Scroll-wave Dynamics in Cardiac Tissue: (1) Spiral- and Scroll-Wave Turbulence; (2) Spiral- and Scroll-Wave dynamics in Anatomically and Physiologically realistic Mathematical Models for Canine and Human Ventricular Tissue
A summary of the main results of our studies is given below. In most of our work, we use three mathematical models for cardiac myocytes, namely, the Panfilov model, the Aliev-Panfilov model, and the Hund-Rudy-Dynamic ... -
Numerical studies of three dimensional turbulence with polymer additives and two dimentional tubulence thin films
Our study contrasts clearly dissipation-reduction phenomena in homogeneous, isotropic turbulence and drag reduction in wall-bounded flows. In both these cases, the polymers increase the overall viscosity of the solution ... -
Numerical studies of unsteady boundary layer flow problems
This thesis presents the results of numerical investigations on certain unsteady laminar incompressible boundary?layer flow problems. It consists of an introductory chapter and four main chapters. The introductory chapter ... -
Numerical studies of unsteady double diffusive mixed convective boundary_layer flows
In the present thesis, some problems in unsteady mixed convective boundary-layer flows with double diffusion have been numerically investigated. It consists of five chapters-the first of which is a general introduction to ... -
Numerical Study of Directionality of Ion Ejection In Axially Symmetric Ion Traps
(2013-02-13)In the normal operation of quadrupole ion trap mass spectrometers, the trapped ions are ejected symmetrically through both the upper (detector) and lower(source) endcap electrodes during mass selective boundary ejection ... -
Numerical study of natural convection boundary layer flows
This thesis presents a numerical study of some laminar natural convection boundary layer flows in isothermal and non-isothermal media. It consists of five chapters. The first is an introductory one; the remaining four are ... -
Numerical Study Of Regularization Methods For Elliptic Cauchy Problems
(2011-06-30)Cauchy problems for elliptic partial differential equations arise in many important applications, such as, cardiography, nondestructive testing, heat transfer, sonic boom produced by a maneuvering aerofoil, etc. Elliptic ... -
Numerical Study Of The Complex Dynamics Of Sheared Nematogenic Fluids
(2013-07-17)In this thesis, we have tried to explain the regular and irregular(chaotic) dynamics of worm like micellar solutions on applying shear, through a detailed study of the equation of motion of a nematic order parameter tensor ... -
Numerical Techniques for reconstruction of objects from projections
In this dissertation we consider certain alternative procedures, viz., the g-inverse method as well as an iterative technique based on probabilistic estimation for the reconstruction of objects from their projections. ... -
Observational Aspects Of Core Collapse Supernovae
(2013-10-17)The discovery of several bright supernovae (SNe) in recent years has evoked a great deal of interest in these objects. The study of these objects are of importance not only as probes to the end stages of stellar evolution, ... -
Observational Constraints on Global 21-cm Signal from the Epoch of Reionization
One of the most promising probes of Cosmic Dawn (CD) and Epoch of Reionization (EoR) is the rest-frame global 21-cm signal of neutral hydrogen (HI) produced by the intergalactic medium (IGM) prior to the end of the EoR ... -
Observational constraints on the formation of pre-galactic condensates in the universe.
The distribution of galaxies in the Universe displays structure on a variety of scales, ranging from groups of a few galaxies to rich clusters containing thousands of galaxies. These clusters are in turn clustered to form ...
