Experimental And Theoretical Studies In Fatigue Damage Modeling
(2010-12-07)This thesis has two parts. In the first part, we use the results of new fatigue experiments conducted with variable load levels as well as variable stress ratios to critically assess three (two old and one relatively ... -
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 ... -
Experimental And Theoretical Studies Of Strongly Correlated Multiferroic Oxides
(2011-05-23)This thesis presents the synthesis and investigations of physical and chemical properties of multiferroic materials experimentally as well as theoretically. Multiferroics are materials in which at least two of the three ... -
Experimental And Theoretical Studies On Jet Acoustics
(Indian Institute of Science, 2006-12-14)A systematic research on aeroacoustics conducted around the world for the last few decades has revealed various inherent characteristics of the jet noise radiation. However, a lot more needs to be done for the theoretical ... -
Experimental And Theoretical Studies Towards The Development Of A Direct 3-D Diffuse Optical Tomographic Imaging System
(2014-06-02)Diffuse Optical Tomography is a diagnostic imaging modality where optical parameters such as absorption coefficient, scattering coefficient and refractive index distributions are recovered to form the internal tissue ... -
Experimental Determination And New Correlations For Multi-Component Solid Solubilities In Supercritical Carbon Dioxide
(2016-03-02)The fluids that are operated above their critical temperature and pressure are known as supercritical fluids (SCFs). SCFs replaces the conventional organic solvents in the chemical processes due to their attractive ... -
Experimental investigation into the effect of transverse acoustic excitation over swirling flow and flame
Combustion in gas turbine combustors features complex coupling of fluid dynamics, heat release, and chamber acoustics. Most combustion systems have a tendency to self-excite large amplitudes of pressure and heat release ... -
Experimental Investigation Of Aerodynamic Interference Heating Due To Protuberances On Flat Plates And Cones Facing Hypersonic Flows
(2017-05-24)With the age of hypersonic flight imminent just beyond the horizon, researchers are working hard at designing work-arounds for all the major problems as well as the minor quirks associated with it. One such issue, seemingly ... -
Experimental Investigation of Electrons In and Above Liquid Helium
Electrons on the surface of liquid helium form a nearly ideal 2-dimensional electron system (2DES). An electron density up to 2 × 10^9 cm-2, known as the critical electron density, can be achieved on the liquid helium ... -
Experimental Investigation of Fuel Drop Impact on Unheated and Heated Solid
The modelling of spray-wall interaction encountered in engine combustors relies heavily on studies of single drop impact on heated solid surfaces. In the present thesis, the impact of a single fuel drop on a hot, smooth ... -
Experimental Investigation Of Hypersonic Boundary Layer Modifications Due To Heat Addition And Enthalpy Variation Over A Cone Cylinder Configuration
(2010-12-01)Despite years of research in high speed boundary layer flow, there is still a need for insightful experiments to realize key features of the flow like boundary layer response to different conditions and related transition ... -
Experimental Investigation of Multielectron Bubbles in Liquid Helium
(2017-11-28)Multielectron bubbles (MEBs) are micron sized cavities in liquid helium that contain electrons confined within a nanometer thick layer on the inner surface of a bubble. These objects present a rich platform to study the ... -
Experimental Investigation of Novel High Shear Injector at Elevated Pressure Conditions: Hydrodynamics, Spray and Combustion Characterization
The stringent pollution and emission norms due to the present climate change and global warming have pushed industries to meet these norms and cut down their emission levels. In the same pipeline, the aviation industries ... -
Experimental Investigation Of Rheocasting Using Linear Electromagnetic Stirring
(2011-02-09)In several applications of casting, dendritic microstructure is not desirable as it results in poor mechanical properties. Enhancing fluid flow in the mushy zone by stirring is one of the means to suppress this dendritic ... -
