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. ...
Study of Non-Equilibrium Flow Behind Normal Shock
(2017-12-10)
Normal shock problems in high enthalpy flows are of special interests to aerodynamicists and fluid dynamicists. When the shock Mach number become hypersonic and increasing further, the gas passing through the shock is ...
Mixing Enhancement Studies on Supersonic Elliptic Sharp Tipped Shallow (ESTS) Lobed Nozzles
(2017-11-22)
Rapid mixing and spreading of supersonic jets are two important characteristics in supersonic ejectors, noise reduction in jets and fuel mixing in supersonic combustion. It helps in changing the acoustic and thermal signature ...
Studies on Vortex Breakdown in a Closed Cylinder with a Rotating Endwall
(2018-01-09)
Swirling flows abound in nature and numerous engineering applications. Under conditions which are not completely understood, the swirling cores could undergo a sudden enlargement of their vortex core, leading to a ’vortex ...
Artificial Neural Network Approach For Characterization Of Acoustic Emission Sources From Complex Noisy Data
(Indian Institute of Science, 2006-12-14)
Safety and reliability are prime concerns in aircraft performance due to the involved costs and risk to lives. Despite the best efforts in design methodology, quality evaluation in production and structural integrity ...
A Study on the Effect of Inhomogeneous Phase of Shape Memory Alloy Wire
(2018-05-25)
The present study in this thesis has attempted to resolve one of the key aspects of enhancing predictability of macroscopic behavior of Shape Memory Alloy (SMA) wire by considering variation of local phase inhomogeneity. ...
