Experimental and Numerical Studies on Low Emission Syngas Combustion
The present study concerns experimental and numerical investigation of the combustion of low-calorific value syngas in an optically accessible reverse flow combustion chamber. Several modes of operation are investigated ... -
Experimental and numerical studies on Mode-I ductile fracture behaviour of Magnesium
In recent years, weight reduction of automobiles is being achieved by using light weight metals like magnesium (Mg) in the form of cast or wrought products. However, the structural application of Mg and its alloys is limited ... -
Experimental and Numerical Studies on Phase Shifting in an Inertance Pulse Tube Cryocooler
(2018-06-21)This work is concerned with the design, development and performance evaluation of an inertance Pulse Tube Cryocooler (PTC). The main components of a PTC are the compressor, regenerator, pulse tube and inertance tube coupled ... -
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 ... -
Experimental and Numerical Studies to Strengthen the Adhesive Bonded Single Lap Joint
In this work, an attempt has been made to strengthen the adhesive bonding using various concepts like hybrid joints, dual and mixed adhesive bonded joints. One of the most commonly occurrence of defect in adhesive bonded ... -

Experimental and numerical study of sink flow turbulent boundary layers
Sink flow turbulent boundary layers (TBLs) develop in the incompressible flow be- tween two convergent, plane smooth walls and represent a family of favorable pres- sure gradient TBLs. These are the only smooth wall TBLs ... -
Experimental and Theoretical Insights into Impact Phenomena of Small Scale Liquid Interfacial Systems
This work explores impact phenomena experimentally and theoretically for various interfacial systems ranging from medical diagnostics to drop impacts on solids and immiscible liquids. We study a hitherto unexplored impact ... -
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 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 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 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 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 ... -
