Thermal Behaviour Of Mono-Fibre Composites And Hybrid Composites At Cryogenic Temperatures
(2013-01-31)Hybrid composites forms an important field of research in the area of composite science and engineering as it gives the advantage of avoiding complex lay-up designs and provides better tuning compatibility to get desired ... -
Three Dimensional Computational Fluid Dynamic Simulation and Analysis of a Turbocharger Compressor
(2018-05-01)This thesis constitutes detailed computational investigation on ow through the passages of a centrifugal compressor used for turbocharging applications. Given the dynamic nature of operation of the turbocharger, it becomes ... -
Time Scale Separated Nonlinear Partial Integrated Guidance And Control Of Endo-Atmospheric Interceptors
(2011-03-17)To address the concern of classical guidance and control designs (where guidance and control loops are designed separately in an “outer loop – inner loop” structure), integrated guidance and control (IGC) ideas have been ... -
Time-Optimal Guidance for Impact Angle Constrained Interception of Moving Targets
(2018-05-30)Various unmanned missions deploy vehicles such as missiles, torpedoes, ground robots, and unmanned aerial vehicles. Guidance strategies for these vehicles aim to intercept a target point and satisfy additional objectives ... -
Transition Zone In Constant Pressure Boundary Layer With Converging Streamlines
(Indian Institute of Science, 2007-04-18)The laminar-turbulent transition in viscous fluid flows is one of the most intriguing problems in fluid dynamics today. In view of the enormous applications it has in a variety of fields such as aircraft design, turbomachinery, ... -
Turbulence Modeling for Predicting Flow Separation in Rocket Nozzles
(2018-01-30)Convergent-Divergent (C-D) nozzles are used in rocket engines to produce thrust as a reaction to the acceleration of hot combustion chamber gases in the opposite direction. To maximize the engine performance at high ... -
Turbulence-Premixed Flame Interactions
The interaction between premixed flames and turbulence is an inherently non-linear phenomenon. Understanding such interactions has profound practical implications towards the development of better combustion devices and ... -
Turbulent Jet Diffusion Flame : Studies On Lliftoff, Stabilization And Autoignition
(2010-07-09)This thesis is concerned with investigations on two related issues of turbulent jet diffusion flame, namely (a) stabilization at liftoff and (b) autoignition in a turbulent jet diffusion flame. The approach of Conditional ... -
Turbulent Near Wake Behind An Infinitely Yawed Flat Plate
(Indian Institute of Science, 2005-09-20)Near wake is the region of wake flow just behind the trailing edge of the body where the flow is strongly influenced by the upstream flow conditions and also perhaps by the characteristics of the body. The present work ... -
Two Problems on the Parametric Resonances and Bifurcations in Rotating Beams
The current research work addresses two interesting systems related to rotating beams. The first dynamical system under consideration is an articulated uniform beam rotating in vacuum under vertical hub excitation along ... -
UAV Group Autonomy In Network Centric Environment
(2016-11-23)It is a well-recognized fact that unmanned aerial vehicles are an essential element in today’s network-centric integrated battlefield environment. Compared to solo UAV missions, multiple unmanned aerial vehicles deployed ... -
Ultra High Compression For Weather Radar Reflectivity Data
(2007-10-09)Weather is a major contributing factor in aviation accidents, incidents and delays. Doppler weather radar has emerged as a potent tool to observe weather. Aircraft carry onboard radars but their range and angular resolution ... -
