An experimental study of bubble parameters in subcooled flow boiling in vertical channel to validate different heat flux partitioning models
(2019-05-10)
Pressurized water reactors (PWR) are safely operating below maximum heat flux
conditions because actual heat flux partitioning models fail to predict it accurately. Improving the
heat flux models will lead to more efficient ...
Numerical simulation and experimental validation of the re-design of high Tc current leads for the astro-E2 X-Ray spectrometer detector system
(2003-12)
The herein presented research work consists on the redesign and thermal model development of the X-Ray Spectrometer (XRS) High Tc Superconducting Current (HTSC) lead assembly. The HTSC leads are used to provide current to ...
Hydrogen transport behavior and phase decomposition of AISI-321 austenitic stainless steel via cathodic polarization
(2007)
Room temperature cathodic polarization of AISI-321SS austenitic stainless steel in aqueous electrolytic H2SO4 with hydrogen recombination inhibitor (Na2HAsO4) generated phase decomposition on the subsurface layer of the ...
Direct numerical simulation of turbulent channel flow with V-shape turbulators
(2010)
Direct Numerical Simulations (DNS) are carried out to study the channel flow V-shaped roughness on both wall. The roughness is modeled by the immerse boundary method for passive heat transport in a turbulent channel flow ...
A study of the corrosion resistance of gamma titanium aluminide in ringer's solution, 3.5 WT% NaCI and seawater
(2005)
Corrosion resistance is one of the essential requirements that determine the application of a metallic alloy as a biomaterial. The titanium alloy, gamma titanium aluminide (γTiAl), widely known for its low density, high ...
Natural-convection heat transfer in supercritical fluids
(2004)
The main objective of this study is to calculate the heat-transfer coefficients for natural convection from a heated, vertical flat plate into a supercritical fluid. In the first part of this work, an equation for the ...
Performance comparison between inverse kinematic algorithms on 6R robotic manipulators
(2013)
One of the most important aspects of controlling a robotic manipulator is the solution of its Inverse Kinematics problem. Numerical methods, although more computationally challenging than algebraic or geometric methods, ...
Characterization of a microfluidic device for autonomous biological cell entrapment and electrical interrogation
(2011)
Microfluidic devices have become a great tool to target biological cells individually. They are easy to manufacture, involve short time assays, use small sample and reagent volumes, and usually have low Reynolds number ...
Thermomechanometric study of AI-Cu-B composites reinforced with diboride particles
(2011)
Al-Cu composites reinforced with diboride particles were fabricated by gravity casting. A thermomechanical analysis (TMA) system allowed studying hardness and creep behavior of the composites. The composite hardness was ...
Damage assessment under repeated slamming and creep of foam core sandwich composites
(2013)
Sandwich composites are increasingly being used in the ship hull design due mainly to (i) their high strength to weight ratio, and (ii) the ability to functionally grade them for a broad range of commercial and naval ...
