Interface capturing in multiphase flows using finite volume based level set method
An important class of problems involves a substance transforming from one phase to another with absorption or emission of energy. Such cases arise in many settings, of which melting, solidification, condensation, and ... -
The use of dual quaternions in rigid body motion interpolation and visualization
Dual quaternions are an excellent alternative tool to transformation matrices in the study of rigid body motion. They are known to represent the position and orientation of a rigid body in a concise and efficient manner, ... -
Constrained least squares finite element formulation of two-dimensional elastodynamic problems
In the present work, a least?squares finite element formulation for two?dimensional elastodynamic problems is developed. This development is based on an earlier formulation reported by Pratap. The earlier formulation was ... -
Rational approach to solid finite elements
The finite element method today has become a powerful tool in engineering analysis and design. The ease of application, reliability of solutions, and its ability to model complex geometries seem to be the main reasons for ... -
Electronic signal processing in laser doppler annemometry
The three commonly used electronic processors for laser Doppler anemometer systems are the spectrum analyser, the frequency tracking demodulator and the period timing device. Extensive analytical studies on spectrum analyser ... -
An Experimental Study On The Scale Effects In Cavitation Noise
Cavitation noise studies were made in a water tunnel with particular reference to scale effects. Travelling?bubble cavitation was artificially generated on four axisymmetric bodies of the Schiebe head?forms with varying ... -
Boundary layer transition with and without lateral divergence
Information on the transition processes in turbomachine boundary layers is important in computing schemes for predicting blockage, flow losses, separation, etc. Actual transition on turbomachine blades does not conform to ... -
Experimental study of endwall flow in a compressor cascade
Improvement in calculating methods for end?wall boundary layers of blade rows can only come about by a greater understanding of the physics of the flow from which realistic models can be built of the terms that go into ... -
Studies on viscosity of mixtures of freon-12 and freon 22 vapours
The viscosity of pure Freon?12 and Freon?22 vapours, and their mixtures, has been determined using an oscillating?disc viscometer at room temperature and pressure. The results agree well with the published data for the ... -
Studies on viscosity of mixtures of some freon vapours
An oscillating disc viscometer is used for the determination of viscosity of Freon?12, Freon?22 and Freon?114 vapours and their binary and ternary mixtures at room temperature and pressure. The viscosity of Freon?12, ... -
Effect of trade addition of tin on the isothermal and di- isothermal geing characteristic of anlminium- magnesium 0.26 silicon alloy
Pre?precipitation and precipitation processes in quenched supersaturated solid solutions of age?hardenable alloy systems are known to be vacancy?aided phenomena. The clustering kinetics would be significantly altered when ... -
Benificiation Studies on Low Grade Tungsten Dposits of Degana, Rajasthan
The unique high?temperature properties of tungsten and its alloys are responsible for increased demand for this metal, particularly in the forms of carbide and pure metal. It is also an important strategic material for ... -
Bioleaching of a lean grade chalcopyrite ore : studies on amenability and mechanisms
The role of bacteria in the leaching of mineral sulphides is discussed with respect to Thiobacillus ferrooxidans. Column leaching studies were carried out on Malanjkhand lean?grade chalcopyrite ore samples using Thiobacillus ... -
Thermodynamic properties of p-xylene - chloroethans
The importance of accurate thermodynamic data of pure substances and mixtures in research and industry hardly needs any emphasis. Apart from their utility in process design calculations, such data are useful in theoretical ... -
Studies in dehydrochlorination of 1,1, 2, 2 Tetrachloroethane
Dehydrochlorination of tetrachloroethane is studied both in homogeneous as well as in heterogeneous phases. The feasibility of the reaction has been evaluated from thermodynamic considerations. The reaction is found to ... -
studies on oxidation of anthracene
Anthraquinone is an important dye intermediate. The demand for anthraquinone in India is likely to go up in the next few years, making its manufacture promising. Among the various methods, vapour phase catalytic oxidation ... -

Thermodynamic properties of toluene chloroethane systems
The thesis embodies experimental data on (i) vapour pressure, (ii) vapour–liquid equilibria, (iii) heats of mixing at 25 and 35°C, and (iv) latent heats of vaporization for the systems toluene and chloroethanes. Vapour–liquid ... -
Studies on dealkylation of alkyl aromatic hydrocarbons Part II- Demithylation of xylene isomers and ethylebezene to benzene
The demand for benzene is increasing. The possibilities of preparing it from substituted benzene by dealkylation are investigated in the present work. From the literature pertaining to dealkylation processes, the vapour?phase ...
