In the flying field of space transportation domain, the increased efforts involving design and development of hypersonic flight for space missions is on toe to provide the optimum aerothermodynamic design data to satisfy ...
Effective Property Estimation of Carbon Composites using Micromechanical Modeling
(2018-02-28)
In recent times, composite materials have gained mainstay acceptance as a structural material of choice due to their tailorability and improved thermal, specific strength/stiffness and durability performance. Carbon-Carbon ...
Some Experimental and Numerical Studies on Evaluation of Adhesive Bond Integrity of Composites Lap Shear Joints
(2018-03-02)
Adhesive bonding which has been in use for long as a traditional joining method has gained ground in the last couple of decades due to the introduction of advanced composite materials into the aerospace industry. Bonded ...
Vision-based Strategies for Landing of Fixed Wing Unmanned Aerial Vehicles
(2018-05-14)
Vision-based conventional landing of a fixed wing UAV is addressed in this thesis. The work includes mathematical modeling, interface to a software for rendering the outside scenery, image processing techniques, control law ...
Hybird Central Solvers for Hyperbolic Conservation Laws
(2018-05-11)
The hyperbolic conservation laws model the phenomena of nonlinear waves including discontinuities. The coupled nonlinear equations representing such conservation laws may lead to discontinuous solutions even for smooth ...
A Ghost Fluid Method for Modelling Liquid Jet Atomization
(2018-05-21)
Liquid jet atomisation has a wide variety of application in areas such as injectors in automobile and launch vehicle combustors, spray painting, ink jet printing etc. Understanding physical mechanisms involved in the primary ...
Effect of a Mesh on Boundary Layer Transition Induced by Free-stream Turbulence and an Isolated Roughness Element
(2018-06-23)
A high level of free-stream turbulence and surface roughness are known to cause breakdown of an otherwise stable laminar flow. In transition induced by free-stream turbulence, streaks are formed due to the lift-up effect ...
Analysis of Unsteady Incompressible Potential Flow Over a Swimming Slender Fish and a Swept Wing Tail
(2018-05-16)
This thesis deals with computing the pressure distribution around a swimming slender fish
and the thrust generated by its flapping motion. The body of the fish is modeled as a missile like slender body to which a tail is ...
Wave Transmission Characteristics in Honeycomb Sandwich Structures using the Spectral Finite Element Method
(2017-12-12)
Wave propagation is a phenomenon resulting from high transient loadings where the duration of the load is in µ seconds range. In aerospace and space craft industries it is important to gain knowledge about the high frequency ...
