Phase transitions of fluids confined in nanopores
Confined nanoscale fluids occur in many technologically important phenomenon such as boundary lubrication, adsorption, adhesion and catalysis. Fluids confined at these length scales are spatially inhomogeneous and fluid ... -
Linear stability analysis of fluid flow adjacent to a flexible surface
Fluid flow adjacent to a flexible surface is often encountered in biological systems and bio-technological processes. These flows have been analyzed using models similar to those for the flow past a rigid surface, but the ... -
Studies of instabilities in particulate suspensions
The focus of this project is to study the dynamics of particulate suspensions. This study is divided into two parts. Part one focuses on the dynamics of self-propelled particles, such as microorganisms. The dynamics of ... -
Frictional-kinetic models for steady cohesionless granular flow through a wedge-shaped hopper
The present work attempts to combine a newly developed kinetic constitutive theory with an older frictional theory to model.the two-dimensional gravity flow of a cohesionless granular material such as sand through a ... -
Some flow problems in noncoaxial rotating systems
We live in an atmosphere of air and water which involve rotation to a greater or lesser extent. The atmosphere and the oceans rotate as a whole with the earth and move over its surface as winds and ocean currents which ... -
Electromagnetic waves in plasmas
This thesis embodies the investigations on the electromagnetic waves in plasmas. The investigations fall under two general headings, namely, wave propagation in plasmas in the presence of the Coriolis force (Part I) and ... -
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 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 investigations of unsteady incompressible boundary - layer flows
This thesis presents a numerical study of some problems in unsteady, laminar incompressible boundary-layer theory. It is divided into five chapters, the first being a general introduction to boundary-layer theory with ... -
Swiriling flows between rotating coaxial and non-coaxial disks
In this thesis an attempt is made to study some steady and unsteady flow problems due to a single rotating disk and two disks rotating coaxially or non-coaxially in different fluid media in a variety of interesting situations. ... -
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 ... -
Studies in laminar boundary layer theory with suction or injection
Chapter I deals with the solution of the full Navier-Stokes equations in the neighbourhood of the leading edge in the presence of suction. We obtain exact solution further downstream on the basis of boundary layer equations ... -
Similar solutions in nonequilibrium nozzle flows
The phenomena of thermal and/or chemical nonequilibrium in flowing gases at high temperatures is of fundamental importance in rocket nozzles as well as hypersonic flight simulation facilities. The present state-of-the-art ... -
Bursting phenomenon in turbulent flows
The importance of the phenomenon of bursts in turbulent shear layers has been recognised by fluid dynamicists during the past few years. Kline et al. (1967), Corino & Brodkey (1969), and more recently Grass (1971) noticed ...
