Advanced Thermal Energy Systems Based On Paraffin Waxes Applicable In Building Industry
Sobolciak, Patrik; Karkri, Mustapha; Krupa, Igor; Al Maadeed, Mariam ( Hamad bin Khalifa University Press (HBKU Press) , 2014 , Conference Paper)Thermal energy storage systems are crucial for reducing dependency on fossil fuels and minimizing CO2 emissions. The building sector is a major sector responsible for producing high levels of CO2 in most countries (including ... -
Improvement of thermal conductivity of paraffin by adding expanded graphite
Karkri, Mustapha; Lachheb, Mohamed; Gossard, Didier; Ben Nasrallah, Sassi; AlMaadeed, Mariam A ( SAGE Publications Ltd , 2016 , Article)This paper investigated the use of graphite with different configuration designs to improve the thermal energy storage of phase change material systems. Two types of graphite have been combined with paraffin in order to ... -
