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 ... -
Chilling and feeding narrow freezing range alluminium alloy
A detailed investigation was carried out to study the solidification behaviour of narrow freezing range Aluminium-12% Silicon alloy (modified) - LM 6 plate and cylindrical castings cast in dry sand moulds, the feeding of ... -
Corrosion and related electrochemical studies on ziroconium (in nitrate melts, nitrats fluoride melts and aqueous nitrate solutions)
The thesis embodies the results of the investigations on the corrosion of zirconium in nitrate melts. The predicted thermodynamic behaviour of zirconium in 2-component NaNO?-KNO? eutectic melts based on E-pO diagrams ... -
Kinetic investigations on gas solid reactions
Gas-Solid Reactions in Metallurgical Processes Gas-solid reactions are of current interest to process metallurgists because of their growing importance in industrial processes. In the present work, investigations were ... -
Oxidation of Alcohols
Oxidation of ethanol and methanol are known to be feasible reactions. Equilibrium constants calculated show that these reactions are highly irreversible. Theoretically ethanol and methanol oxidations to their respective ... -
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 ... -
Strength behaviour including stress-strain relations of clays-
Stability problems for their analysis and design necessitate an assessment of appropriate strength parameters of a given soil system. In soil masses, since deformations result largely from slippages between soil particles, ... -
Studies in a trickle-bed reactor
Trickle bed reactors are widely used in petroleum industries and to a limited extent in chemical industries. In these reactors, a liquid reactant (or a liquid containing a reactant) trickles over a fixed bed of catalyst ... -
Studies on characteristics of cavity and cavitation damage behind circular cylinders in water with a venturi
Cavitation is a complex hydrodynamic phenomenon involving the appearance, growth and collapse of vapour- and/or gas-filled bubbles. During the collapse phase, it generates forces sufficient to erode even the strongest ... -
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 ... -
Vapour phase catalytic hydrogenation of aniline
A very large effort has been directed towards heterogeneous catalysis and establishing the proper form for equations that express the rate of surface reactions as a function of system variables. These equations range ... -
Vapour phase oxidation of p-xylene
The kinetic study on the oxidation of p-xylene has been carried out. The oxidation of p-xylene on the following two catalysts has been studied: (a) tin vanadate (b) ferric molybdate (Boreskov’s composition) Ferric molybdate ...
