Static And Dynamic Calibration Of A Multi-component Sidewall Force Balance For A Transonic Ludwieg Tube Wind Tunnel
(Aerospace Engineering, 2012-04-11)
Experimentation involving transonic flow requires replicating not only the Mach number but also the Reynolds number. Improper matching of the Reynolds number affects the interaction between the shocks and boundary layer ...
Using GPU-based Computing To Accelerate Finite Element Problems
(Aerospace Engineering, 2012-07-25)
Historically Graphics Processing Units (GPU) have been used for offloading graphical visualization and made popular in use for video games, but with the development of NVIDIA's CUDA architecture and programing language ...
Control Of Airship Motion In The Presence Of Wind
(Aerospace Engineering, 2012-07-25)
This research effort develops a guidance and control system for a small airship to fly through assigned waypoints in the three dimensional space with a desired speed in the presence of wind and wind gust. In the control ...
Design, Calibration And Testing Of A Force Balance For A Hypersonic Shock Tunnel
(Aerospace Engineering, 2012-07-25)
The forces acting on a flight vehicle are critical for determining its performance. Of particular interest is the hypersonic regime. Force measurements are much more complex in hypersonic flows, where those speeds are ...
New Developments In Cognitive Optimization
(Mechanical Engineering, 2012-07-25)
This work presents an approach to solve function optimization problems using cognitive optimization. A cognitive search algorithm which is developed mimics human cognition in structure and characteristics. This algorithm ...
CFD Analysis Of Direct Evaporative Cooling Zone Of Air-side Economizer For Containerized Data Center
(Mechanical Engineering, 2012-07-25)
Conventional data centers are extremely large buildings that have complex power distribution and cooling systems. These traditional brick and mortar data centers employ relatively expensive cooling systems and are inefficient. ...
Filling Of Methane/air Mixture In A Tube For Pulse Detonation Engines
(Mechanical Engineering, 2012-04-11)
In pulse detonation engines, filling is a time consuming process; reducing these times will help to increase the frequency. The filling of a detonation tube, 1 m long tube with an internal diameter of 101.6 mm, closed at ...
Design And Modeling Techniques For Cooling Of Telecommunication Systems
(Mechanical Engineering, 2012-04-11)
Conventional data centers are extremely large buildings that have complex power distribution and cooling systems. These traditional brick and mortar data centers employ relatively expensive cooling systems and are inefficient. ...
Adaptation Of Digital DATCOM Into A Conceptual Design Process
(Aerospace Engineering, 2012-04-11)
As implied with open-ended `design decision-making' there are multiple prospective conventional and unconventional aircraft solution concepts able to satisfy a given mission specification. The task of defining, assessing ...
Plate Analysis With Different Geometries And Arbitrary Boundary Conditions
(Mechanical Engineering, 2012-04-11)
This thesis work deals with the study of plates with various geometries and different boundary conditions. The method of study is carried out mainly using the Galerkin method combined with the help of the symbolic algebraic ...
