A Study On Boundary Layer Transition Induced By Large Freestream Disturbances
(2013-06-12)
The initial slow viscous growth of the Tollmein-Schlichting wave in a canonical boundary layer transition is absent in bypass and wake-induced transitions. Although there have been a great deal of studies pertaining to ...
Differential Evolution Based Interceptor Guidance Law
(2013-05-29)
Kinematics based guidance laws like the proportional navigation (PN) and many other linear optimal guidance laws perform well in near-collision course conditions. These have been studied thoroughly in the literature from ...
Measurement Of Static Pressure Over Bodies In Hypersonic Shock Tunnel Using MEMS-Based Pressure Sensor Array
(2013-10-08)
Hypersonic flow is both fascinating and intriguing mainly because of presence of strong entropy and viscous interactions in the flow field. Notwithstanding the tremendous advancements in numerical modeling in the last ...
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 ...
Active Vibration Control Synthesis Using Viscoelastic Damping Phenomena
(2011-07-12)
In this thesis, a new method is followed to design an active control system which imparts viscoelastic phenomenological damping in an elastic structure. Properties of a hypothetical viscoelastic system are used to design ...
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 ...
Micro-Blast Waves
(2014-09-02)
The near field blast–wave propagation dynamics has been a subject of intense research in recent past. Since experiments on a large scale are difficult to carry out, focus has been directed towards recreating these blast ...
Energy Separation And Lox Separation Studies In Vortex Tubes
(2014-11-24)
Vortex Tube (VT) is a simple device having no moving mechanical parts, in which compressed gas at high pressure is injected through one or more tangential nozzles into a vortex chamber resulting in the separation of the ...
LU-SGS Implicit Scheme For A Mesh-Less Euler Solver
(2014-10-10)
Least Square Kinetic Upwind Method (LSKUM) belongs to the class of mesh-less method that solves compressible Euler equations of gas dynamics. LSKUM is kinetic theory based upwind scheme that operates on any cloud of points. ...
