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 ... -
Innovative method of metal coating of microcapsules containing phase change materials
Al-Shannaq, Refat; Kurdi, Jamal; Al-Muhtaseb, Shaheen; Farid, Mohammed ( Elsevier Ltd , 2016 , Article)Microencapsulation of phase change materials (PCMs) is needed to prevent PCM leaking during melting. However, the low thermal conductivity of the microcapsules shell limits their applications. To enhance thermal conductivity ... -
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 ...
