Experimental Study Of Large Angle Blunt Cone With Telescopic Aerospike Flying At Hypersonic Mach Numbers
(2011-04-06)The emerging and competitive environment in the space technology requires the improvements in the capability of aerodynamic vehicles. This leads to the analysis in drag reduction of the vehicle along with the minimized ... -
Experimental Study Of Plasma Actuator Characteristics And Optimization Of Configuration
(2013-06-26)Plasma actuators are devices which function by creating a discharge in air at atmospheric conditions. These devices have been demonstrated to effectively delay flow separation and enhance the lift- drag characteristics of ... -
Experimental Study On The Impact Of Water Drops On Groove-Textured Surfaces
(2014-09-08)The interaction of a liquid drop with a solid surface is being actively studied to understand practically encountered scenarios such as the impact of fuel spray droplets onto the walls of engine combustion chamber, the ... -
Experiments on the Late Stages of Boundary Layer Transition
(2018-03-19)In canonical boundary layer transition, a uniform laminar flow perturbed by 2-d T-S waves develops downstream into 3-d waves, which eventually break down with turbulent spots appearing. Previous experimental studies have ... -
Experiments on Varying Intensity Air Blasts in Shock Tubes
Abstract In the recent past, with an increasing number of terrorist activities, blast related research has focused on conducting careful experiments to develop newer protection strategies. As field experiments using ... -
Explicit Filtering LES for turbulent premixed flames
Large eddy simulations of a premixed, turbulent, methane-air round jet flame at an equivalence ratio of 0.8 and unburnt gas temperature of 800 K are performed using Explicit Filtering LES (EFLES) method. The nominal inflow ... -
Flame Particle Tracking Analysis of Turbulence-Premixed Flame Interaction
This work describes the computational and theoretical developments made in the understanding of turbulence-premixed flame interaction, using both lean and rich H2-air mixtures, in a flow field of near-isotropic turbulence. ... -
Fluid-Elastic Interactions in Flutter And Flapping Wing Propulsion
(2017-10-06)This study seeks to understand the interplay of vorticity and elasto-dynamics that forms the basis for a fluttering flag and flapping wing propulsion, and factors that distinguish one from the other. The fluid dynamics is ... -
Flutter Identification and Aeroelastic Stability during Wake Penetration
Demonstration of utter stability over the design envelope and identi fication of safe ight envelope is a prerequisite for operational clearance of any new aircraft design. An important step involved in flight flutter ... -
Flutter Susceptibility Assessment of Airplanes in Sub-critical Regime using Ameliorated Flutter Margin and Neural Network Based Methods
(2018-02-17)As flight flutter testing on an airplane progresses to high dynamic pressures and high Mach number region, it becomes very difficult for engineers to predict the level of the remaining stability in a flutter-prone mode and ... -
From Particles to People: Vicsek-Inspired Behavioural Modelling Frameworks
In this thesis, we develop different modelling frameworks to capture the processes of opinion formation and disease spread. The common theme binding them is a nearest-neighbour-based interaction rule; while the closeness ... -
Fuel Drop Splashing on Heated Solid Surfaces
Droplet-wall interactions on heated surfaces are significantly encountered in applications such as fuel spray impingement in combustors and spray cooling. The present thesis is focused on the splashing of fuel drops on ... -
A Generalised Modelling of Piezoelectric Composite Shells and Plates using Variational Asymptotic Method
In several fields of engineering, researchers are actively pursuing the possibility to use smart materials such as piezoelectric composites in order to make the structure smart. Piezoelectric materials have the capability ... -
Genetic Programming Based Multicategory Pattern Classification
(Indian Institute of Science, 2005-02-22)Nature has created complex biological structures that exhibit intelligent behaviour through an evolutionary process. Thus, intelligence and evolution are intimately connected. This has inspired evolutionary computation ... -
