Instabilities In Supersonic Couette Flow
(2010-07-15)
Compressible plane Couette flow is studied with superposed small perturbations. The steady mean flow is characterized by a non-uniform shear-rate and a varying temperature across the wall-normal direction for an appropriate ...
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 ...
Investigations On Film Cooling At Hypersonic Mach Number Using Forward Facing Injection From Micro-Jet Array
(2010-07-16)
A body in a hypersonic flow field will experience very high heating especially during re-entry. Conventionally this problem is tackled to some extent by the use of large angle
blunt cones. At the cost of increased drag, ...
Autonomous Landing Of Unmanned Aerial Vehicles
(2010-03-26)
In this thesis the problem of autonomous landing of an unmanned aerial vehicle named AE-2 is addressed. The guidance and control technique is developed and demonstrated through numerical simulation results. The complete ...
Wing in Ground Effect
(2017-12-01)
The thesis presents a two pronged approach for predicting aerodynamics of air- foils/wings in the vicinity of the ground. The first approach is effectively a model for ground effect studies, employing an inexpensive Discrete ...
Experimental Studies on Shock-Shock Interactions in Hypersonic Shock Tunnels
(2017-12-16)
Shock-shock interactions are among the most basic gas-dynamic problem, and are almost unavoidable in any high speed light, where shock waves generating from different sources crosses each other paths. These interactions ...
Kinetic Streamlined-Upwind Petrov Galerkin Methods for Hyperbolic Partial Differential Equations
(2017-09-20)
In the last half a century, Computational Fluid Dynamics (CFD) has been established as an important complementary part and some times a significant alternative to Experimental and Theoretical Fluid Dynamics. Development ...
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 ...
Guidance Laws for Engagement Time Control
(2017-12-16)
Autonomous aerial vehicles like missiles and unmanned aerial vehicles (UAVs) have attracted various military and civilian applications. The primary guidance objective of any autonomous vehicle is to reach the desired ...
Atomization Characteristics of Camelina and Jatropha-Derived Drop-in Aviation Biofuels
(2017-11-22)
Biofuels in civil aviation is actively studied in recent years to identify potential alternative jet fuels to meet stringent environmental regulations imposed to tackle degraded air quality caused by fossil fuel combustion. ...
