Optimal Control Of Numerical Dissipation In Modified KFVS (m-KFVS) Using Discrete Adjoint Method
(2010-06-04)
The kinetic schemes, also known as Boltzmann schemes are based on the moment-method-strategy, where an upwind scheme is first developed at the Boltzmann level and after taking suitable moments we arrive at an upwind scheme ...
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, ...
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. ...
Experimental Investigation Of Hypersonic Boundary Layer Modifications Due To Heat Addition And Enthalpy Variation Over A Cone Cylinder Configuration
(2010-12-01)
Despite years of research in high speed boundary layer flow, there is still a need for insightful experiments to realize key features of the flow like boundary layer response to different conditions and related transition ...
Investigation Of Ramp/Cowl Shock Interaction Processes Near A Generic Scramjet Inlet At Hypersonic Mach Number
(2010-08-05)
One of the major technological innovations that are necessary for faster and cheaper access-to-space will be the commercial realization of supersonic combustion jet engines (SCRAMJET). The establishment of the flow through ...
Multi-Agent Search Using Voronoi Partition
(2010-08-05)
This thesis addresses a multi-agent search problem where several agents, equipped with sensors and communication devices, search an unknown area. Lack of information about the search space is modeled as an uncertainty ...
The Effect Of Energy Deposition In Hypersonic Blunt Body Flow Field
(2010-09-23)
A body exposed to hypersonic flow is subjected to extremely high wall heating rates, owing to the conversion of the kinetic energy of the oncoming flow into heat through the formation of shock waves and viscous dissipation ...
Motion Optimistion Of Plunging Airfoil Using Swarm Algorithm
(2010-06-03)
Micro Aerial Vehicles (MAVs) are battery operated, remote controlled miniature flying vehicles. MAVs are required in military missions, traffic management, hostage situation surveillance, sensing, spying, scientific, rescue, ...
A Study Of A Vortex Particle Method For Vortex Breakdown Phenomena
(2010-07-06)
Vortex breakdown is an important phenomenon observed in swirling flows involving the development of a stagnation point on the axis of the vortex followed by a region of recirculation when the swirl increases beyond a ...
