Optimization Of The Tool Path In A Robotic Environment
(Mechanical Engineering, 2007-08-23)
The rising costs and demand coupled with shrinking energy generating resources has triggered the need for optimum use of energy resources, minimizing the overhead costs and maximizing the profits. Robots have been long ...
An Experimental Investigation Of Ionization Of Supersonic Air By A Corona Discharge
(Aerospace Engineering, 2007-08-23)
A technique is developed to ionize supersonic air flow in a shock tube by a weak corona discharge. The driven section of the tube is open to the atmosphere. The shock propagates in the driven section at about 1 km/s by ...
Enhancement Of Pool Boiling Heat Transfer Using Thermally-conductive Microporous Coating Techniques
(Mechanical Engineering, 2007-08-23)
The present research is an experimental study of the enhancement of boiling heat transfer using microporous coating techniques. The current research is divided into four major phases. During the first phase, the effects ...

Crashworthiness Design Optimization Using Surrogate Models
(Mechanical Engineering, 2007-08-23)
Despite the advances in computer technology, the enormous computational cost associated with the large-scale and complex nonlinear crashworthiness simulations renders it to be impractical to rely exclusively on computer ...
Analysis And Optimal Design Of Beams Using Radial Basis Function
(Mechanical Engineering, 2007-08-23)
The application of Multiquadric Radial Basis Function (MQ RBF) in the analysis and optimal design of beams are addressed in this dissertation. For static analysis, a new Least Square Collocation (LSC) method is introduced. ...
Arc-heated Gas Flow Experiments For Hypersonic Propulsion Applications
(Aerospace Engineering, 2007-08-23)
Although hydrogen is an attractive fuel for a hypersonic air-breathing vehicle in terms of reaction rate, flame temperature, and energy content per unit mass, the substantial tank volume required to store hydrogen imposes ...
Numerical Study Of Chemically Reacting Viscous Flow Relevant To Pulsed Detonation Engines
(Aerospace Engineering, 2007-08-23)
A computational fluid dynamics code for two-dimensional, multi-species, laminar Navier-Stokes equations is developed to simulate a recently proposed engine concept for a pulsed detonation based propulsion system and to ...
