Development of Green Inhibitors to Prevent Hydrates Formation, Protect Environment and Reduce Energy Cost in Oil and Gas Industry
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Gas hydrates are identified as ice-liked solid, crystalline compounds having polyhedral water cavities, where gas molecules get trapped during operation under high pressure and low temperature condition. These hydrates ...
Solar Thermochemical CO2 Utilization via Ceria Based Redox Cycle
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
According to the recent studies, it is expected that the global energy requirement will increase from 14 TW to 30 TW by the year 2050. Currently, fossil fuels are the major energy source utilized for the fulfillment of the ...
Performance Analysis of Multiphase High Power Open End Drives Fed from Dual Matrix Converter
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
In this paper an open ended seven phase stator winding drive is considered for analysis that is to be fed from matrix converter controlled by space vector pulse width modulation scheme. Open-end winding variable speed ...

Enhanced Energy Extraction from a Solar Panel
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Due the movement of the sun throughout the day, the insolation level incident on the fixed panel surface varies largely. The maximum level of insolation occurs only around noon. This leads to the panel to be under-utilised. ...
