Acoustic Source Characterization Of The Exhaust And Intake Systems Of I.C. Engines
(2010-07-15)For an engine running at a constant speed, both exhaust and intake processes are periodic in nature. This inspires the muffler designer to go for the much easier and faster frequency domain modeling. But analogous to ... -
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 ... -
Conjugate Natural Convection In Horizontal Annuli

Coupled Heat Transfer Processes in Enclosed Horizontal Heat Generating Rod Bundles
(2018-03-24)In a nuclear fuel cask, the heat generating spent fuel rods are packed in a housing and the resulting bundle is placed inside a cask of thick outer shell made of materials like lead or concrete. The cask presents a wide ... -
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 ... -
Development Of A Single Cylinder SI Engine For 100% Biogas Operation
(Indian Institute of Science, 2007-05-21)This work concerns a systematic study of IC engine operation with 100% biogas as fuel (as opposed to the dual-fuel mode) with particular emphasis on operational issues and the quest for high efficiency strategies. As a ... -
Development Of An Advanced Methodology For Automotive IC Engine Design Optimization Using A Multi-Physics CAE Approach
(2016-09-14)The internal combustion engine is synonyms with the automobile since its invention in late 19th century. The internal combustion engine today is far more advanced and efficient compared to its early predecessors. An intense ... -

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 And Numerical Studies On Flame Stability And Optimization Of A Compact Trapped Vortex Combustor
(2013-03-27)A new Trapped Vortex Combustor (TVC) concept has been studied for applications such as those in Unmanned Aerial Vehicles (UAVs) as it offers potential for superior flame stability and low pressure loss. Flame stability is ... -
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. ... -
Laminar Conjugate Natural Convection And Surface Radiation In Horizontal Annuli
(2010-07-29)Numerical studies of two-dimensional laminar conjugate natural convection flow and heat transfer in horizontal annuli formed between inner heat generating solid cylinders and outer isothermal circular boundary are performed ... -
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 ... -
Numerical Simulations Of Two-Phase Reacting Flow In A Cavity Combustor
(2013-05-28)In the present work, two phase reacting flow in a single cavity Trapped Vortex Combustor (TVC) is studied at atmospheric conditions. KIVA-3V, numerical program for simulating three dimensional compressible reacting flows ... -
