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 ... -
Single Cavity Trapped Vortex Combustor Dynamics : Experiments & Simulations
(2011-04-06)Trapped Vortex Combustor (TVC) is a relatively new concept for potential use in gas turbine engines addressing ever increasing demands of high efficiency, low emissions, low pressure drop, and improved pattern factor. This ... -
Stability Of Double-Diffusive Finger Convection In A Non-Linear Time Varying Background State
(2010-09-06)Convection set up in a fluid due to the presence of two components of differing diffusivities is known as double diffusive convection. Double diffusive convection is observed in nature, in oceans, in the formation of certain ... -
Studies On Automization And Sprays Of Plant Oil Biofuels Using Laser-Based Diagnostics
(2014-12-12)Atomization characteristics of liquid fuel sprays control combustion efficiency and emissions in engines. The present work is motivated by the need to study the atomization and spray structure of vegetable oil biofuels for ... -
Studies On Fuel-Air Stratification And Combustion Modelling In A CNG-Fuelled Engine
(2016-11-19)In-cylinder fuel-air mixing in a compressed natural gas (CNG)-fuelled, single-cylinder, spark-ignited engine is analysed using a transient three-dimensional computational fluid dynamic model built and run using STAR-CD, a ... -
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 ... -
Study Of Liquid Fuel Film Transport And Its Effect On Cold Start Hydrocarbon Emissions In A Carburetted Engine
(2013-01-31)The present work is concerned with fundamental studies on the liquid fuel transport in the intake manifold of small carburetted engines. This work is motivated by the need for development of technologies to meet the stringent ... -
Theoretical And Experimental Studies Of Capillary Pumped Loop And Loop Heat Pipe
(2010-07-13)Capillary pumped loop (CPL) and loop heat pipe (LHP), are two-phase heat transport devices which rely on surface tension induced by a fine pore wick to drive a working fluid in a loop. These are based on a working principle ... -
Thermodynamic Analysis And Simulation Of A Solar Thermal Power System
(2014-05-21)Solar energy is a virtually inexhaustible energy resource, and thus, has great potential in helping meet many of our future energy requirements. Current technology used for solar energy conversion, however, is not cost ... -
Topology Optimization Of Composite Heat-Sinks Involving Phase-Change Material
(2010-08-16)The principal goal of this thesis is to develop a systematic method for the design of composite heat sinks (CHSs) that serve as passive and transient cooling devices for microelectronics. This is accomplished by posing the ... -
Tribology Of Combustion Generated Soot
(2016-11-19)Soot is a carbonaceous materials produced as a result of incomplete combustion of fuels (gasoline, diesel, etc). At the present level of automobile technology, emission of soot from combustion in diesel engine appears to ... -
