A Numerical Study of Droplet Dynamics in Viscoelastic Flows
(2017-10-05)
The polymers are integral part of vast number of products used in day to day life due to their anomalous viscoelastic behaviour. The remarkable flow behaviour exhibited by the polymeric fluids including rod climbing, ...
Design And Development Of Miniature Compliant Grippers For Bio-Micromanipulation And Characterization
(2017-05-24)
Miniature compliant grippers are designed and developed to manipulate biological cells and characterize them. Apart from grippers, other compliant mechanisms are also demonstrated to be effective in manipulation and ...
Analytical Investigations on Linear And Nonlinear Wave Propagation in Structural-acoustic Waveguides
(2017-09-26)
This thesis has two parts: In the first part, we study the dispersion characteristics of structural-acoustic waveguides by obtaining closed-form solutions for the coupled wave numbers. Two representative systems are ...
Development And Investigation of Two-Stage Silica Gel + Water Adsorption Cooling Cum Desalination System
(2017-09-20)
The present research work caters to two important needs of rural India: i) desalination of subsoil/coastal brackish water and ii) basic refrigeration for short term preservations of agro-produce, medicines etc. Fortunately, ...
Unsteady Two Dimensional Jet with Flexible Flaps at the Exit
(2017-11-13)
The present thesis involves the study of introducing passive exit flexibility in a two dimensional starting jet. This is relevant to various biological flows like propulsion of aquatic creatures (jellyfish, squid etc.) and ...
Novel Compression Fracture Specimens And Analysis of Photoelastic Isotropic Points
(2017-10-11)
Compression fracture specimens are ideally suited for miniaturization down to tens of microns. Fracture testing of thermal barrier coatings, ceramics and glasses are also best accomplished under compression or indentation. ...
Growth And Characterization of ZnO Nanostructures for Device Applications : Field Emission, Memristor And Gas Sensors
(2017-11-09)
Zinc oxide (ZnO) is perhaps one of the most widely studied material in the last two decades. It has received so much of attention because of its incredible potential for wide ranging applications. ZnO is a wide band gap ...
Robust Finite Element Strategies for Structures, Acoustics, Electromagnetics and Magneto-hydrodynamics
(2017-12-13)
The finite element method (FEM) is a widely-used numerical tool in the fields of structural dynamics, acoustics and electromagnetics. In this work, our goal is to develop robust FEM strategies for solving problems in the ...
Laser-based Diagnostics and Numerical Simulations of Syngas Combustion in a Trapped Vortex Combustor
(2017-11-16)
Syngas consisting mainly of a mixture of carbon monoxide, hydrogen and other diluents, is an important fuel for power generation applications since it can be obtained from both biomass and coal gasification. Clean coal ...
Stall Flutter of a Cascade of Blades at Low Reynolds Number
(2017-12-05)
Due to the requirements for high blade loading, modern turbo‐machine blades operate very close to the stall regime. This can lead to flow separation with periodic shedding of vortices, which could lead to self induced ...
