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 ...
Non-Dimensional Kinetoelastic Maps for Nonlinear Behavior of Compliant Suspensions
(2018-02-18)
Compliant suspensions are often used in micromechanical devices and precision mechanisms as substitutes for kinematic joints. While their small-displacement behavior is easily captured in simple formulae, large-displacement ...
Motion Space Analysis of Smooth Objects in Point Contacts
(2018-07-19)
The present work studies instantaneous motion of smooth planar and spatial objects in unilateral point contacts. The traditional first-order instantaneous kinematic analysis is found insufficient to explain many common ...
Dynamics of Bubbles and Drops in the Presence of an Electric Field
(2018-07-16)
The present thesis deals with two-phase electrohydrodynamic simulations of bubble and droplet dynamics under externally applied electric fields. We used the Coupled Level-Set and Volume-of-fluid method (CLSVOF) and two ...
Vibrational Energy Harvesting : Design, Performance and Scaling Analysis
(2018-07-12)
Low-power requirements of contemporary sensing technology attract research on alternate power sources that can replace batteries. Energy harvesters function as power sources for sensors and other low-power devices by ...
Insights into Instabilities in Burning and Acoustically Levitated Nanofluid Droplets
(2018-07-16)
The complex multiscale physics of nanoparticle laden functional droplets in a reacting environment is of fundamental and applied significance for a wide variety of applications ranging from thermal sprays to pharmaceutics ...
Characterization of Flow Induced Noise Received by an Array Placed at Stagnation Point of an Underwater Axisymmetric Body
(2018-07-09)
Given the interest on underwater axisymmetric cylindrical bodies for the development of high-speed underwater weapons, characterization of the boundary layer flow-induced noise received by a Sound NAvigation and Ranging ...
Modeling Free Surface Flows and Fluid Structure Interactions using Smoothed Particle Hydrodynamics
(2018-06-26)
Recent technological advances are based on effectively using complex multiphysics concepts. Therefore, there is an ever increasing need for accurate numerical al-gorithms of reduced complexity for solving multiphysics ...
Heterogeneous Object Modelling : Representation, Construction and Process Planning
(2018-06-26)
Heterogeneous Objects are engineered with multiple materials to achieve multiple functionalities like high hardness, high toughness and low structural weight. Heterogeneous objects are increasingly used to achieve multiple ...
