Turbulence Modeling for Predicting Flow Separation in Rocket Nozzles
(2018-01-30)
Convergent-Divergent (C-D) nozzles are used in rocket engines to produce thrust as a reaction to the acceleration of hot combustion chamber gases in the opposite direction. To maximize the engine performance at high ...
Modeling and Simulation of Biomolecular Flow in Microchannel
(2018-01-01)
Microfluidics deals with the behavior, control and manipulation of fluids which are confined at micrometer length scale. It has important application in lab-on-a chip technology, micro-propulsion, additive manufacturing, ...
Microgravity Flow Transients in the Context of On-Board Propellant Gauging
(2018-02-15)
It is well known that surface tension of a liquid has a decisive role in flow dynamics and the eventual equilibrium state, especially in confined flows under low gravity conditions and also in free surface flows. One such ...
Optimal Guidance Of Aerospace Vehicles Using Generalized MPSP With Advanced Control Of Supersonic Air-Breathing Engines
(2016-07-11)
A new suboptimal guidance law design approach for aerospace vehicles is proposed in this thesis, followed by an advanced control design for supersonic air-breathing engines. The guidance law is designed using the newly ...
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 ...
Cyclic Pursuit : Variants and Applications
(2018-02-11)
The classical n-bugs problem has attracted considerable attention from researchers. This problem stems from the study of movement of a group of animals. In the context of multi- agent systems the problem has been modelled ...
UAV Group Autonomy In Network Centric Environment
(2016-11-23)
It is a well-recognized fact that unmanned aerial vehicles are an essential element in today’s network-centric integrated battlefield environment. Compared to solo UAV missions, multiple unmanned aerial vehicles deployed ...
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 ...
A Residual Based h-Adaptive Strategy Employing A Zero Mean Polynomial Reconstruction
(2016-04-18)
This thesis deals with the development of a new adaptive algorithm for three-dimensional fluid flows based on a residual error estimator. The residual, known as the R –parameter has been successfully extended to three ...
