Power Loss Minimization for Drag Reduction and Self-Propulsion using Surface Mass Transpiration
(2017-11-29)The remarkable efficacy with which normal surface mass transpiration (blowing and suction) alters a given base flow to achieve a desired predefined objective has motivated several investigations on drag reduction, ... -
Pragmatic Design of Compliant Mechanisms using Selection Maps
(2018-04-02)A pragmatic method for designing compliant mechanisms is developed in this thesis, by selecting among existing mechanisms one that may be modified as required. This method complements existing techniques by answering ... -
Quantitative Laser-Based Diagnostics and Modelling of Syngas-Air Counterflow Diffusion Flames
(2018-06-05)Syngas, a gaseous mixture of H2, CO and diluents such as N2, CO2, is a clean fuel generated via gasification of coal or biomass. Syngas produced via gasification typically has low calorific values due to very high dilution ... -
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 ... -
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 ... -
Simulation and Study of Noise Generated due to Turbulent Boundary Layer in Towed Hydrophone Array
In this thesis, a wave propagation based analytical model is developed for an underwater towed array. The towed array is modeled as an in finite tube filled with a certain liquid and submerged in an in finite volume of ... -
Specification and Verification of Tolerances for Parts with Free-Form Surfaces
(2017-11-27)The need for increased product variety and improved aesthetics require the manufacturing enterprise to reduce time to market and to increase use of free-form surfaces in the form of the product. These changes lead to ... -
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 ... -
Static Balancing of Rigid-Body Linkages and Compliant Mechanisms
(2018-03-07)Static balance is the reduction or elimination of the actuating effort in quasi-static motion of a mechanical system by adding non-dissipative force interactions to the system. In recent years, there is increasing recognition ... -
Studies for Design of Layered Ceramic Armour Inspired by Seashells
(2018-06-26)Pearly layers in seashells, also known as nacreous layers, are reported to be three orders of magnitude tougher than their primary constituent, aragonite. Their high toughness is attributed to a particular structure of ... -

Studies on Multiphase, Multi-scale Transport Phenomena in the Presence of Superimposed Magnetic Field
(2018-02-28)Multiphase transport phenomena primarily encompass the fundamental principles and applications concerning the systems where overall dynamics are precept by phase change evolution. On the other hand, multiscale transport ... -
Studies on the Design of Novel MEMS Microphones
(2018-02-17)MEMS microphones have been a research topic for the last two and half decades. The state-of-the-art comprises surface mount MEMS microphones in laptops, mobile phones and tablets, etc. The popularity and the commercial ... -
Studies on the Effect of Process Aspects on Material Mixing and Defect Formation in Friction Stir Welding
(2018-05-30)Friction Stir Welding (FSW) is a rapidly growing solid state welding process and has been a proven method for welding high strength aluminium alloys which were formerly not recommended for joining by conventional fusion ... -
