Combustion Instability Screech In Gas Turbine Afterburner
(2009-08-04)Gas turbine reheat thrust augmenters known as afterburners are used to provide additional thrust during emergencies, take off, combat, and in supersonic flight of high-performance aircrafts. During the course of reheat ... -
Demonstration Of Supersonic Combustion In A Combustion Driven Shock-Tunnel
(2011-01-17)For flights beyond Mach 6 ramjets are inefficient engines due to huge total pressure loss in the normal shock systems, combustion conditions that lose a large fraction of the available chemical energy due to dissociation ... -
Dynamics Of Water Drops Impacting Onto The Junction Of Dual-Textured Substrates Comprising Hydrophobic And Hydrophilic Portions
(2014-11-24)The research topic of liquid drop interaction with solid surfaces is being actively pursued to gain in-depth understanding of several practical cases such as the impingement of fuel spray droplets on surfaces like combustion ... -
Experimental Measurement Of Flame Response To Acoustic Oscillations
(2014-06-20)Acoustic instabilities in a combustion chamber arise due to the coupling of acoustic pressure with in-phase heat-release, and are characterized by large amplitude oscillations of one or more natural modes of combustor. ... -
Momentum And Enthalpy Transfer In Packed Beds - Experimental Evaluation For Unsteady Inlet Temperature At High Reynolds Numbers
(2013-06-10)Solid propellant gas generators that have high gas capacity are used for fast pressurization of inflatable devices or elastic shells. However, many applications such as control surface actuation, air bottle pressurization ... -
Parametric Analysis Of A Free Piston Stirling Engine For Spacecraft Power Applications With A Radioisotope Heat Source
(2014-07-11)Stirling engines are promising candidates for applications where air breathing engines cannot be used. Self contained engines capable of operating independently of the environment are required to convert thermal energy ... -
Premixed Turbulent Combustion Of Producer Gas In Closed Vessel And Engine Cylinder
(2010-10-22)Producer gas derived from biomass is one of the most environment friendly substitutes to the fossil fuels. Usage of producer gas for power generation has effect of zero net addition of CO2 in atmosphere. The engines working ... -
Role Of Hydrogen Injection Temperature On The Combustion Instability Of Cryogenic Rocket Engine
(2014-04-16)Physical mechanism for high frequency instability in cryogenic engines at low hydrogen injection temperature has been a subject of debate for long time. Experimental and early developmental studies revealed no instabilities ... -
Studies On Impinging-Jet Atomizers
(2009-05-06)Characteristics of impinging-jet atomizers in the context of application in liquid propulsion systems are studied in this thesis. A review of past studies on impinging jets revealed the necessity of a correlation in terms ... -
Turbulent Jet Diffusion Flame : Studies On Lliftoff, Stabilization And Autoignition
(2010-07-09)This thesis is concerned with investigations on two related issues of turbulent jet diffusion flame, namely (a) stabilization at liftoff and (b) autoignition in a turbulent jet diffusion flame. The approach of Conditional ...
