Numerical Study Of Low Mach Number Conjugate Natural Convection And Radiation In A Vertical Annulus
(2010-07-23)
The problem of low Mach number (non-Boussin´esq) conjugate laminar natural convection combined with surface radiation in a vertical annulus with a centrally located vertical heat generating rod is studied numerically, ...
Glowworm Swarm Optimization : A Multimodal Function Optimization Paradigm With Applications To Multiple Signal Source Localization Tasks
(2009-05-05)
Multimodal function optimization generally focuses on algorithms to find either a local optimum or the global optimum while avoiding local optima. However, there is another class of optimization problems which have the ...
Mode-3 Asymptotic Analysis Around A Crack Embedded In A Ductile Functionally Graded Material
(2009-09-15)
Functionally graded materials (FGMs) are composites with continuous material property variations. The distinct interfaces between the reinforcement and the matrix in classical composites are potential damage initiation ...
Design, Development And Flight Control Of Sapthami - A Fixed Wing Micro Air Vehicle
(2010-09-21)
Two micro air vehicles, namely Sapthami and Sapthami-flyer, are developed in this thesis. Their total weight is less than 200grams each. They fit inside a 30cm and 32cm sphere respectively and carry the commercially available ...
Experimental Investigation Of The Effect Of Nose Cavity On The Aerothermodynamics Of The Missile Shaped Bodies Flying At Hypersonic Mach Numbers
(2010-06-01)
Hypersonic vehicles are exposed to severe heating loads during their flight in the atmosphere. In order to minimize the heating problem, a variety of cooling techniques are presently available for hypersonic blunt bodies. ...
Residual Error Estimation And Adaptive Algorithms For Fluid Flows
(2011-03-16)
The thesis deals with the development of a new residual error estimator and adaptive algorithms based on the error estimator for steady and unsteady fluid flows in a finite volume framework. The aposteriori residual error ...
Design And Development Of Diaphragmless Hypersonic Shock Tunnel
(2011-03-16)
The growing requirements to achieve hypersonic flights, as in the case of reentry vehicles, pose a serious challenge to the designers. This demands an understanding of the features of hypersonic flow and its effect on ...
