Transition and Acoustic Response of Vortex Breakdown Modes in Unconfined Coaxial Swirling Flow and Flame
(2018-07-19)
The efficient and enhanced mixing of heat and incoming reactants is achieved in modern gas turbine systems by employing swirling flows. This is realized by a low velocity region (internal recirculation zone -IRZ) zone ...
Role of Microstructure in the Mechanics of Soft Matter
(2018-07-16)
Materials which exhibit non-linear mechanical behaviors under large deformations are generally classified as “soft matter”. Elastomers represent an important class of soft materials which have wide commercial applications ...
Dynamics of Hollow Cone Spray in an Unconfined, Isothermal, Co-Annular Swirling Jet Environment
(2018-07-20)
The complex multiphase flow physics of spray-swirl interaction in both reacting and non-reacting environment is of fundamental and applied significance for a wide variety of applications ranging from gas turbine combustors ...
Design Of Two-Axis Displacement-Amplifying Compliant Mechanisms Using Topology Optimization
(2010-07-14)
This thesis deals with the design of two-axis displacement-amplifying compliant mechanisms (DaCMs) using topology optimization. The two-axis compliant mechanisms considered here are XY positioners and two-axis inertial ...
Transport Phenomena In Laser Surface Alloying: A Numerical Investigation
(Indian Institute of Science, 2006-08-24)
A comprehensive, transient three-dimensional model of a single-pass laser surface alloying process has been developed and used to examine the heat, momentum and species transport phenomena. A numerical study is performed ...
Cylindrical Fretting And Delamination : Axisymmetric Static And Dynamic Analysis
(2011-01-17)
Axisymmetric analysis of cylindrical contacts is considered in the context of axisymmetric assemblies such as shrink-fits. Fretting fatigue induces sub-critical cracks along the contact interface of press fits especially ...
A Novel Hybrid Vehicle Architecture : Modeling, Simulation and Experiments
(2018-05-22)
Electric and hybrid vehicles are particularly suited for use in urban areas since city transportation is mainly characterized by relatively short driving distances, low continuous power requirements, long idling times and ...
Feasible and Intrinsic Kinetoelastostatic Maps for Compliant Mechanisms
(2018-03-06)
Despite many advances in the design methods for compliant mechanisms, it is still not possible to know if a set of user-specifications has a solution. Furthermore, practical considerations such as failure limits and ...
Experimental and Numerical Studies on Spray in Crossflow
(2018-02-06)
The phenomenon of spray in crossflow is of relevance in gas turbine combustor development. The current work focuses on spray in crossflow rather than liquid jet in crossflow from the standpoint of enhancing fuel dispersion ...
Robust Registration of Measured Point Set for Computer-Aided Inspection
(2018-03-22)
This thesis addresses the problem of registering one point set with respect to
another. This problem arises in the context of the use of CMM/Scanners to inspect
objects especially with freeform surfaces. The tolerance ...
