Design and Development of a Three-degree-of-freedom Parallel Manipulator to Track the Sun for Concentrated Solar Power Towers
(2018-05-21)
In concentrated solar power (CSP) stations, large arrays of mirrors which are capable of changing its orientation are used to reflect the incident solar energy to a stationary receiver kept at a distance. Such mirrors are ...
Influence of Hydrodynamic Slip on the Wake Dynamics and Convective Transport in Flow Past a Circular Cylinder
(2018-06-14)
Hydrodynamic slip is known to suppress vorticity production at the solid-fluid boundary in bluff body flows. This suppression combined with the enhanced vorticity convection results in a substantial reduction in the unsteady ...
Numerical Simulation of a High-speed Jet Injected in a Uniform Supersonic Crossflow Using Adaptively Redistributed Grids
(2018-05-22)
Minimizing numerical dissipation without compromising the robust shock-capturing attributes remains an outstanding challenge in the design of numerical methods for high-speed compressible flows. The conflicting requirements ...
Transition and Acoustic Response of Vortex Breakdown Modes in Unconfined Coaxial Swirling Flow and Flame
(2018-07-19)
The efficient and enhanced mixing of heat and incoming reactants is achieved in modern gas turbine systems by employing swirling flows. This is realized by a low velocity region (internal recirculation zone -IRZ) zone ...
Role of Microstructure in the Mechanics of Soft Matter
(2018-07-16)
Materials which exhibit non-linear mechanical behaviors under large deformations are generally classified as “soft matter”. Elastomers represent an important class of soft materials which have wide commercial applications ...
Dynamics of Hollow Cone Spray in an Unconfined, Isothermal, Co-Annular Swirling Jet Environment
(2018-07-20)
The complex multiphase flow physics of spray-swirl interaction in both reacting and non-reacting environment is of fundamental and applied significance for a wide variety of applications ranging from gas turbine combustors ...
A Novel Hybrid Vehicle Architecture : Modeling, Simulation and Experiments
(2018-05-22)
Electric and hybrid vehicles are particularly suited for use in urban areas since city transportation is mainly characterized by relatively short driving distances, low continuous power requirements, long idling times and ...
Feasible and Intrinsic Kinetoelastostatic Maps for Compliant Mechanisms
(2018-03-06)
Despite many advances in the design methods for compliant mechanisms, it is still not possible to know if a set of user-specifications has a solution. Furthermore, practical considerations such as failure limits and ...
Experimental and Numerical Studies on Spray in Crossflow
(2018-02-06)
The phenomenon of spray in crossflow is of relevance in gas turbine combustor development. The current work focuses on spray in crossflow rather than liquid jet in crossflow from the standpoint of enhancing fuel dispersion ...
Robust Registration of Measured Point Set for Computer-Aided Inspection
(2018-03-22)
This thesis addresses the problem of registering one point set with respect to
another. This problem arises in the context of the use of CMM/Scanners to inspect
objects especially with freeform surfaces. The tolerance ...
