Studies in drop formation
An exhaustive survey of literature has indicated that no investigation has been carried out on drop formation in non?Newtonian fluids. Further, it is noted that little attention has been paid to the problem of drop formation ... -
Investigations on gas-liquid ejectors
A gas–liquid ejector offers relatively higher interfacial area and can be seriously considered as a cocurrent gas–liquid contactor. A model has been proposed, which assumes the contactor comprises a series of stirred vessels ... -
studies on thermal decomposition of calcium carbonate /calcium hydroxide for energy storage
Alternate energy sources are essential to meet the present?day energy demands. Non?conventional energy resources may substitute for natural sources to some extent and they alleviate discomfortable thoughts about the impending ... -
Dynamics of gas bubbles in liquids
The study of bubble formation in liquids is of great importance because of its application in the design of many industrial bubble contactors like distillation columns, bubble cap columns, absorption towers, reactors, extraction ... -
Enzymatic synthesis of esters in supercritical fluids
Lipases are enzymes that are widely used to catalyze a variety of industrially important reactions. However, lipase?catalyzed reactions are heterogeneous and mass?transfer limited. Therefore, in most cases the reaction ... -
Structure and Rheology of Lyotropic Liquid Crystals
The aim of the present work is to probe the structure and rheology of the various lyotropic liquid crystalline substances. For this purpose, a commercial rheometer is used for studying the rheology of the substance and a ... -
Experimental studies on swirling flows at vertically upward intakes
The experimental investigations presented in this thesis are concerned with the aspects of sump geometry and sump parameters, which govern the flow conditions at vertically upward intakes. Detailed studies are made to ... -
Flow characteristics of sharp-edged orifices,quadrant-edged orifices and nozzles
This thesis presents an integrated study of flow past sharp-edged orifices, quadrant-edged orifices and long radius nozzles, covering different aspects such as metering characteristics, loss characteristics and flow ... -
Studies on erosion due to liquid jet impingement
The problem of erosion due to liquid jet impingement and cavitation is gaining importance with the rapid technological progress in the recent years. The possible uses of liquid jets in the mixing processes in chemical ... -
Higher order discrete dipole approximations for solution of light scattering problems

Parallel finite element multigrid solver for incompressible navier-stokes equations
Fluid flows are generally modelled using the Navier-Stokes Equations (NSE). The model can also be applied in the simulation of various practical applications such as weather, ocean currents, air flow over aircrafts, etc. ... -
Antifungal antibiotics by actinomycetes formation of champamycin - B By Streptomyces Champavatii
Presently, the chemotherapeutic treatment of the widely prevalent fungal infections in humans, animals and plants is far from satisfactory and is in marked contrast to that of bacterial diseases which are controlled successfully ... -
Theoretical studies in micropolar and viscoelastic fluids
We record below a summary of the results of our investigations. The linear micropolar fluid is a viscous fluid with five additional coefficients of viscosity, apart from the usual Newtonian fluid. In its flow behaviour it ... -
Analysis of some unsteady laminar boundary - layer flows using numerical methods
This thesis presents the analysis of the numerical investigations of some unsteady laminar incompressible boundary?layer flow problems. It consists of five chapters. The first chapter deals with a general introduction to ... -
Mangnetohydrodynamic flow and diffusion in channels or pipes with some physiological applications

The fate of phase transitions in VO2 on doping
Ever since its discovery more than six decades ago, thermally-induced insulator-metal transition (IMT) in vanadium dioxide (VO2) has attracted much attention, not only because of its near-room temperature IMT at ~340 K, ... -
On The Theory of burning of monopropellant droplets
This thesis is concerned with theoretical investigations on some aspects of monopropellant droplet combustion. The burning characteristics have been obtained by solving the governing differential equations which are ...
