Cavitation and cavitation damage
This thesis deals with the study of certain aspects of cavitation damage. In the first part of the thesis, a critical survey of the existing literature has been made, and various theories of cavitation damage have been ... -
Some Studies on branch channel Flow
In the present investigation, methods are suggested to predict the flow into a branch taking off from a main channel, maintaining subcritical flow in the main and supercritical in the branch channel. The methods are based ... -
Ecologically sound integrated regional energy planning
The central theme of the integrated energy plan would be to prepare an area-based decentralised energy plan to meet energy needs for subsistence and development of alternate energy sources at least cost to the economy and ... -
Simulative performance analysis of ATM switching fabrics
Asynchronous Transfer Mode (ATM) has emerged as the major technology paradigm for the implementation of the Broadband Integrated Digital Services Network (B?ISDN). In ATM, all forms of information such as voice, video and ... -
Oxidation of Sulfur Dioxide with Copper (II) catalyst in aqueous solution and on poly-4-vinylpyridine resin
Air pollution by sulfur dioxide is of great concern due to its harmful effects on environment, human beings, fauna and flora. Thermal power plants and industries employing combustion of carbonaceous fuels are the major ... -
Studies on fluidised-bed electrode
Flowing electrolyte The mass transfer coefficient k between the flowing electrolyte and the outer wall of an annulus in streamline flow varies as … The mass?transfer data obtained in streamline flow in this investigation ... -
Oxidation of ortho-xylene
The thesis embodies the work on the vapour?phase oxidation of o-xylene over sintered and compacted vanadium pentoxide catalyst in a fixed?bed reactor (FBR) and a continuous stirred?tank catalytic reactor (CSTCR). A survey ... -
Chemical process deveoopment for sodium dithionite- a kinetic study of sodium formate process
(1) The kinetics of formation of sodium dithionite has been investigated in homogeneous aqueous phase. The rate of hydrolysis of sodium formate has been found to be the rate?controlling step. The following rate equation ... -
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
Abstract not available -
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. ...
