(2017-04-21)
With the advancement of technology and the development of more sophisticated remote sensing sensor systems, the use of satellite imagery has opened up various fields of exploration and application. There has been an increased ...
Understanding High Speed Mixing Layers with LES and Evolution of Urans Modeling
(2017-11-15)
This thesis is concerned with studies on spatially developing high speed mixing layers with twin objectives: (a) to provide enhanced and detailed understanding of spatial development of two-dimensional mixing layer emanating ...
Delamination Modeling and Detection in Composite Structures
(2017-12-12)
Composite laminated structures are prone to delamination. Rotorcraft flexbeams, apart from many other aerospace primary load carrying members are made up of composite laminated structures. A delaminated primary load carrying ...
Wave Transmission Characteristics in Honeycomb Sandwich Structures using the Spectral Finite Element Method
(2017-12-12)
Wave propagation is a phenomenon resulting from high transient loadings where the duration of the load is in µ seconds range. In aerospace and space craft industries it is important to gain knowledge about the high frequency ...
Shocks, Shock-Boundary Layer Interaction, And Transonic Flutter
(2017-09-27)
Transonic utter is an aeroelastic instability characterized by part-chord shocks over an airfoil and single mode oscillations leading to a drop in the utter boundary. We present a numerical study that examines the influence ...
Multi-Agent Positional Consensus Under Various Information Paradigms
(2017-02-22)
This thesis addresses the problem of positional consensus of multi-agent systems. A positional consensus is achieved when the agents converge to a point. Some applications of this class of problem is in mid-air refueling ...
Experimental Investigation Of Aerodynamic Interference Heating Due To Protuberances On Flat Plates And Cones Facing Hypersonic Flows
(2017-05-24)
With the age of hypersonic flight imminent just beyond the horizon, researchers are working hard at designing work-arounds for all the major problems as well as the minor quirks associated with it. One such issue, seemingly ...
On The Effect Of Material Uncertainty And Matrix Cracks On Smart Composite Plate
(2017-02-22)
Recent developments show the applications of smart structure in different engineering fields. Smart structures can be used for shape and vibration control, structural health monitoring etc. Smart materials can be integrated ...
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 ...
