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 ... -
Computational methods in linear algebra and related problems
The importance of linear algebra can be summarized by the single statement: "Linear Algebra pervades and enriches almost all areas in numerical computation." Ever so many methods are available in literature for the ... -
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 ... -
Some problems in fluid mechanics with special reference to turbomachinery
This thesis includes some investigations on continuum flows through turbomachines and some slip flow problems. Rarefied gas flow through a nozzle is studied with the aim that this may lead to a greater understanding of ... -
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 ... -
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 ... -
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 ... -
Some dual realizations of Bergman and Hardy spaces on convex domains via integral transforms
The Fantappi{\`e} and Laplace transforms identify abstract spaces of analytic functionals with concrete function spaces, converting geometric support conditions into analytic growth conditions. Specifically, the space of ... -
Kobayashi geometry and a metric notion of negative curvature
In this thesis, we study some problems that represent various aspects of Kobayashi geometry. Our problems are, in some sense, motivated by a close examination---which forms a part of this thesis---of a property that may ... -
Finite field computational techniques for exact solution of numerical problems
In this dissertation, we consider the application of residue arithmetic for the exact computation of g-inverses in order to obviate the round-off errors normally associated with their computation. It turns out that for ... -
Secondary flows and heat transfer in non-newtonian fluids
The thesis consists of four chapters. In chapter I we have described the non-Newtonian fluids which we have discussed in the text and have also derived the equations of motion in the systems of coordinates which we have ... -
Stability and allied problems in magnetohydrodynamics
We note that the expressions (1.20)�(1.27) are real for all real values of the angular momentum MMM. In the numerical computations, we fixed V0V_0V0? and MMM, then obtained the values of (r,z)(r, z)(r,z) from the given ... -
Some magneto-hydrodynamical problems with an application to astoronomy
Part A: A steady flow with the effect of a controlling field of low conductivity past a rotating cylindrical surface in the case of a dissipative medium and its corresponding flow past a magnetized sphere. Part B: The ...
