Studies On Momentum, Heat And Mass Transfer In Binary Alloy Solidification Processes
(Indian Institute of Science, 2007-06-06)
The primary focus of the present work is the development of macro-models for numerical simulation of binary alloy solidification processes, consistent with microscopic phase-change considerations, with a particular emphasis ...
Processing And High Temperature Deformation Of Pure And Magnesia Doped Alumina
(Indian Institute of Science, 2005-12-22)
Creep resistance is an important design criterion at high temperatures especially when continuous attempts are made to increase the efficiencies by increasing the operating temperatures. Alumina is an important high ...
Structures, Thermodynamics and Phase Relations in Selected Oxide Systems
(Indian Institute of Science, 2005-02-08)
Understanding of the interrelationship between structure, thermodynamic properties and phase diagrams is very useful for rationalizing the behavior of materials and development of predictive models, which can be used to ...
Cold Model Study Of Formation And Breaking Of Raceway
(Indian Institute of Science, 2005-12-22)
The raceway in the ironmaking blast furnace is a void in front of the hot blast tuyeres where coke and supplementary fuel burn to supply heat to the ironmaking process. The air velocity through the tuyeres is high (around ...
Processing And Characterization Of B4C Particle Reinforced Al-5%Mg Alloy Matrix Composites
(Indian Institute of Science, 2005-12-22)
Metal matrix composites (MMCs) are emerging as advanced engineering materials for application in aerospace, defence, automotive and consumer industries (sports goods etc.). In MMCs, a metallic base material is reinforced ...
Studies On Biodegradation Of Organic Flotation Collectors Using Bacillus polymyxa
(Indian Institute of Science, 2005-12-22)
Numerous organic reagents of diverse structural composition are employed in the froth flotation process for the beneficiation of non-metallic and sulphide ores. Alkyl xanthates are used as collectors for sulphide ores while ...
Pulsed Laser Ablation Deposition of Intermetallic Thin Films: A Study of Evolution of Metastable Phases and Ultra-fine Microstructures
(Indian Institute of Science, 2005-07-27)
This thesis is devoted to the deposition of intermetallic thin films by laser ablation deposition (LAD) and their characterization. Pulsed laser ablation and subsequent deposition of the ablated vapours produces films under ...
Bubble Solid Interaction
(Indian Institute of Science, 2005-03-09)
The interaction of a bubble with solid surfaces, hydrophobic and hydrophilic, was investigated. When a bubble approaches towards a solid surface, a thin liquid film forms between them. The liquid in the film drains until ...
Role Of Interfacial Phenomena In Bioprocessing Of Minerals Using Bacillus Polymyxa
(Indian Institute of Science, 2006-12-11)
In recent years there has been growing interest in bio-mineral processing due to its low operating costs and its application in processing lean-grade ores. Bioprocessing is a good alternative to conventional hydrometallurgy ...
Modeling Constitutive Behavior And Hot Rolling Of Steels
(Indian Institute of Science, 2006-03-17)
Constitutive behavior models for steels are typically semi-empirical, however recently neural network is also being used. Existing neural network models are highly complex with a large network structure i.e. the number ...
