Study of Non-Equilibrium Flow Behind Normal Shock
(2017-12-10)
Normal shock problems in high enthalpy flows are of special interests to aerodynamicists and fluid dynamicists. When the shock Mach number become hypersonic and increasing further, the gas passing through the shock is ...
Mixing Enhancement Studies on Supersonic Elliptic Sharp Tipped Shallow (ESTS) Lobed Nozzles
(2017-11-22)
Rapid mixing and spreading of supersonic jets are two important characteristics in supersonic ejectors, noise reduction in jets and fuel mixing in supersonic combustion. It helps in changing the acoustic and thermal signature ...
Studies on Vortex Breakdown in a Closed Cylinder with a Rotating Endwall
(2018-01-09)
Swirling flows abound in nature and numerous engineering applications. Under conditions which are not completely understood, the swirling cores could undergo a sudden enlargement of their vortex core, leading to a ’vortex ...
A Study on the Effect of Inhomogeneous Phase of Shape Memory Alloy Wire
(2018-05-25)
The present study in this thesis has attempted to resolve one of the key aspects of enhancing predictability of macroscopic behavior of Shape Memory Alloy (SMA) wire by considering variation of local phase inhomogeneity. ...
Mechanical Characterization of Carbon Nanotubes and Nanocomposites
(2018-08-14)
Measurement of all the mechanical properties of carbon nanotubes is extremely difficult because of its small size. In the present work, all the five transverse isotropic properties of single wall carbon nanotubes (SWCNTs) ...
Analytical Modelling and Non-linear Characterisation of Piezoelectric Materials for Actuation and Vibration Control of Beams
(2018-08-29)
The use of piezoelectric materials for actuation, and vibration suppression of thin beams, is the subject of study in this doctoral thesis. The initial focus is set on reducing beam vibrations with resistively shunted ...
Investigations on Supersonic Flow in Miniature Shock Tubes
(2018-08-02)
The emerging paradigms of shockwave research have opened up new horizons for interdisciplinary applications. This has inevitably driven research towards studying the propagation of shockwaves in miniature shock tubes (tube ...
Experimental and Theoretical Studies of Liquid Drop Impact on Solid Surfaces Comprising Smooth and Texture Portions
(2018-08-10)
Solid surfaces featuring a spatial variation of surface wettability along particular directions on their surface, referred to as wettability gradient surfaces, are becoming increasingly important in practical applications ...
Advanced Optimal Control Design for Nonlinear Systems including Impulsive Inputs with Applications to Automatic Cancer Treatment
(2018-08-14)
The motivation of this research is to propose innovative nonlinear and optimal control design algorithms, which can be used in real life. The algorithms need to be computationally efficient, should deal with control ...
Modelling Simulation and Statistical Studies of Primary Fragmentation of Coal Particles Subjected to Detonation Wave
(2018-08-11)
Coal is likely to remain an important energy source for the next several hundred years
and hence advances in coal combustion technologies have major practical impact. Detonation combustion of coal initiated by a plasma ...
