Convection in a differentially heated rotating spherical shell of Boussinesq fluid with radiative forcing
(2012-12-01)
In this study we investigate the
flow of a Boussinesq
fluid contained in a rotating, differentially heated spherical shell. Previous work, on the spherical shell of Boussinesq fluid, differentially heated the shell by ...
Development of a new hybrid photochemical/electrocatalytic water splitting reactor for hydrogen production: design, analysis and experiments
(2012-01-01)
Solar-driven water splitting combines several attractive features for sustainable
energy utilization. The conversion of solar energy to a type of storable energy has crucial
importance. An alternative method to hydrogen ...
Kinetics and transport phenomena in the chemical decomposition of copper oxychloride in the thermochemical Cu-CI Cycle
(2012-04-01)
The thermochemical copper-chlorine (Cu-Cl) cycle for hydrogen production
includes three chemical reactions of hydrolysis, decomposition and electrolysis. The
decomposition of copper oxychloride establishes the high-temperature ...
Multi-dimensional modeling of transient transport phenomena in molten carbonate fuel cells
(2012-06-01)
Molten carbonate fuel cells (MCFCs) have become an attractive emerging technology for
stationary co-generation of heat and power. From a technical perspective, dynamic operation has
a significant effect on the fuel cell ...
Thermal management of the copper-chlorine cycle for hydrogen production: analytical and experimental investigation of heat recovery from molten salt
(2012-08-01)
Hydrogen is known as a clean energy carrier which has the potential to play a major role in addressing the climate change and global warming, and thermochemical water splitting via the copper-chlorine cycle is a promising ...
Fluid transport and entropy production in electrochemical and microchannel droplet flows
(2012-04-01)
The growth of energy demand in the world requires addressing the increasing
power requirements of industrial and residential consumers. Optimizing the design of
new and existing large power producing systems can efficiently ...
Analytical modeling and simulation of metal cutting forces for engineering alloys
(2012-04-01)
In the current research, an analytical chip formation model and the methodology to determine material flow data have been developed. The efforts have been made to address work hardening and thermal softening effects and ...
Conceptual design of a thermal hydraulic loop for multiple test geometries at supercritical conditions named supercritical phenomena experimental test apparatus (SPETA)
(2012-04-01)
The efficiency of nuclear reactors can be improved by increasing the operating pressure of current nuclear reactors. Current CANDU-type nuclear reactors use heavy water as coolant at an outlet pressure of up to 11.5 MPa. ...
The motivational effects of using mobile devices in mathematics classrooms by students with exceptionalities
(2012-04-01)
Low motivation levels experienced by students with exceptionalities in the area of mathematics are often cited as a major factor negatively affecting their potential for success (Baird & Scott, 2009; Reichrath, de Witte, ...
Teachers' views of their technology-focused preservice education program
(2012-04-01)
This study explores the effectiveness of a technology-focused preservice education program by interviewing practicing teachers who have graduated from the program. The views of the teachers are examined with reference to ...
