A rapid method for low temperature microencapsulation of phase change materials (Pcms) using a coiled tube ultraviolet reactor
Ansari, Jawaad A.; Al-Shannaq, Refat; Kurdi, Jamal; Al-Muhtaseb, Shaheen A.; Ikutegbe, Charles A.; Farid, Mohammed M.... more authors ... less authors ( MDPI , 2021 , Article)Microencapsulation of phase change materials (PCMs) remain a suitable option within building materials, as they contribute to the thermal mass and provide an energy buffer, an added benefit. This paper presents a novel ... -
Efficacy of using slurry of metal-coated microencapsulated PCM for cooling in a micro-channel heat exchanger
Roberts, Nathan S.; Al-Shannaq, Refat; Kurdi, Jamal; Al-Muhtaseb, Shaheen A.; Farid, Mohammed M. ( Elsevier , 2017 , Article)This paper provides a method of heat transfer enhancement using microencapsulated phase change material (MPCM) slurries, utilizing the latent heat of PCM during melting. The values of heat transfer coefficient obtained for ... -
Emulsion stability and cross-linking of PMMA microcapsules containing phase change materials
Al-Shannaq, Refat; Farid, Mohammed; Al-Muhtaseb, Shaheen; Kurdi, Jamal ( Elsevier , 2015 , Article)The microencapsulation of paraffin as a phase change material (PCM) using poly methyl methacrylate (PMM) as a shell was investigated by means of suspension polymerization. The increase in the emulsion stability by using ... -
Supercooling elimination of phase change materials (PCMs) microcapsules
Al-Shannaq, Refat; Kurdi, Jamal; Al-Muhtaseb, Shaheen; Dickinson, Michelle; Farid, Mohammed ( Elsevier , 2015 , Article)Microencapsulated phase change materials (PCM) must not experience any supercooling, otherwise cannot be used in any latent heat applications. In this study Rubitherm®RT58 and1-octadecanol were selected as nucleating agents ...
