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 ...
An Experimental Study Of Instabilities In Unsteady Separation Bubbles
(Indian Institute of Science, 2007-06-11)
The present thesis is an experimental study of some aspects of unsteady two dimensional boundary layers subject to adverse pressure gradient. An adverse pressure gradient usually leads to boundary layer separation or an ...
Analysis And Design Of Spatial Manipulators : An Exact Algebraic Approach Using Dual Numbers And Symbolic Computation
(2008-11-03)
This thesis presents a unified framework for the analysis of instantaneous kinematics and statics of spatial manipulators. The proposed formulation covers the entire range of kinematic behavior, with kinematic singularity ...
Development Of Efficient Modeling Methodologies Of Adhesively Bonded Joints For Crash Simulations
(2009-03-12)
In this thesis, a new modeling methodology applicable to adhesively bonded joints for crash simulations is presented. Using this approach, adhesive joints can be modeled without using minute solid elements thus reducing ...
Studies On The Dynamics And Stability Of Bicycles
(2009-02-25)
This thesis studies the dynamics and stability of some bicycles. The dynamics of idealized bicycles is of interest due to complexities associated with the behaviour of this seemingly simple machine. It is also useful as ...
Unsteady Flow Field Downstream Of A Sudden Expansion
(2009-04-02)
Separating and reattaching flows are important in a large number of engineering configurations. The flow through a sudden expansion (backward-facing step) represents a conceptually simple case of this class of flows and hence ...
The Effect Of Viscosity On The Erosion Of Gradient- Zone In A Laboratory Solar Pond
(Indian Institute of Science, 2006-08-24)
Double diffusive phenomena occur in many natural systems and in a variety of engineering applications, such as solar ponds. In a solar pond, the erosion of gradient zone due to convection and diffusion is the main cause ...
