Shock Tunnel Investigations On Hypersonic Separated Flows
(2009-08-11)Knowledge of flow separation is very essential for proper understanding of both external and internal aerothermodynamics of bodies. Because of unique flow features such as thick boundary layers, merged shock layers, strong ... -
Site Characterization And Seismic Hazard Analysis With Local Site Effects For Microzonation Of Bangalore
(2010-05-25)Seismic hazard and microzonation of cities enable to characterize the potential seismic areas that need to be taken into account when designing new structures or retrofitting the existing ones. Study of seismic hazard and ... -
Strength And Deformation Behaviour Of Jointed Rocks : An Equivalent Continuum Model
(2009-06-30)Most rock masses encountered in civil and mining engineering projects contain pre-existing discontinuities. These discontinuities weaken the rock masses to an extent, which depends very much on the size of engineering ... -
Structural Health Monitoring Of Composite Structures Using Magnetostrictive Sensors And Actuators
(2009-07-14)Fiber reinforced composite materials are widely used in aerospace, mechanical, civil and other industries because of their high strength-to-weight and stiffness-to-weight ratios. However, composite structures are highly ... -
Studies In Stability Of Newtonian And Viscoelastic Fluid Flow Past Rigid And Flexible Surfaces
(2010-09-23)The surface oscillations in a deformable wall are known to induce an instability in the adjacent flow even in the absence of inertia. This instability, if understood properly, can be exploited to generate a well-mixed flow ... -
Studies On Acid Production Potential Of Some Sulphide Minerals And Bioremediation Of Acid Mine Drainage
(2009-08-19)Acid mine drainage (AMD) is a worldwide environmental problem associated with the mining wastes, generated from active and inactive mining sites from mineral processing activities. AMD is defined as the drainage that occurs ... -
Studies On Impinging-Jet Atomizers
(2009-05-06)Characteristics of impinging-jet atomizers in the context of application in liquid propulsion systems are studied in this thesis. A review of past studies on impinging jets revealed the necessity of a correlation in terms ... -
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 ... -
Study Of Evaluation Of Texture And Microstructure During Different Modes Of Rolling And Annealing Of Two Phase α-β Brass
(2010-09-28)It is well known that texture and microstructure play a crucial role in determining properties of metallic materials. The evolution of microstructure and texture during deformation and annealing of copper and some copper ... -
A Study Of Four Nonlinear Systems With Parametric Forcing
(2010-06-01)This thesis considers four nonlinear systems with parametric forcing. The first problem involves an inverted pendulum with asymmetric elastic restraints subjected to harmonic vertical base excitation. On linearizing ... -
Study Of Fracture Properties Of NiAl Bond Coats On Nickel Superalloy By Three Point Bending Of Microbeams
