Advanced Guidance Laws for Field-of-View and Impact Angle Constrained Engagements
This thesis deals with the development of guidance laws for interceptors with seeker field-of-view
(FOV) and impact angle constraints. Two classes of guidance problems, namely, field-of-
view and impact angle constrained ...
Rheological Studies on Slow Flow in Dense Granular Ensembles
An experimental study on the rheology and kinematics of dense granular materials is presented in this thesis in the slow flow regime. In this study, we employ an often used experimental set up of the cylindrical Couette ...
Structural dynamic testing for seismic response simulation and time variant reliability estimation
The research work reported in this thesis addresses a few problems which arise in the context of experimental dynamic testing of engineering structures under earthquake loads. Firstly, we consider the problem of characterizing ...
Flutter Identification and Aeroelastic Stability during Wake Penetration
Demonstration of utter stability over the design envelope and identi fication
of safe ight envelope is a prerequisite for operational clearance of any
new aircraft design. An important step involved in flight flutter ...
Investigations on Impinging Shock Wave and Boundary Layer Interactions in Hypersonic Flow
Shock boundary layer interactions (SBLIs) rank among the most fundamental problems in high-speed aerodynamics and are a primary concern in hypersonic flows. Shocks at hypersonic speeds are typically strong enough to separate ...
Experimental and numerical study of sink flow turbulent boundary layers
Sink flow turbulent boundary layers (TBLs) develop in the incompressible flow be-
tween two convergent, plane smooth walls and represent a family of favorable pres-
sure gradient TBLs. These are the only smooth wall TBLs ...
Adaptive Filtering for Large Eddy Simulation of Flows with Shocks and its Application to Launch Pad Deflectors
During lift-off of launch vehicles jets from nozzles impinge on a wedge deflector which
directs the jet away from the rocket along passages. As a high Reynolds number turbulent
flow the whole region has a broad spectrum ...
Polymer-based investigations into the surface chemistry of some sulphide minerals and the beneficiation of a low grade siliceous copper ore
Tanzania is endowed with rich mineral deposits containing gold, tanzanite, diamond, coal, uranium, iron ore, gemstones with low grade of the sulphide minerals namely chalcopyrite and pyrite. It is the third largest producer ...
Experimental and Numerical Studies on Low Emission Syngas Combustion
The present study concerns experimental and numerical investigation of the combustion of low-calorific value syngas in an optically accessible reverse flow combustion chamber. Several modes of operation are investigated ...
A phenomenological one-dimensional model for elastic ribbons
Ribbons exhibit fascinating buckling-dominated behavior under mechanical loading because of
a unique combination of geometric dimensions. The recent interest in examining engineering
applications of ribbon-like structures ...
