Analysis of the thermal characteristics of the paraffin wax/high-density polyethylene (HDPE) composite as a form-stable phase change material (FSPCM) for thermal energy storage
Dwi Rahmalina, Almira Rahma Zada, Herni Soefihandini, Ismail, Budhi Muliawan Suyitno The present work is specifically focused on the form stability of paraffin as a phase change material (PCM) through the addition of high-density polyethylene (HDPE). The aim of adding HDPE is to obtain a stable form of paraffin during the phase transition. Moreover, improving […]
Examination of patterns in obtaining porous structures from submicron aluminum oxide powder and its mixtures
Edwin Gevorkyan, Volodymyr Nerubatskyi, Yuriy Gutsalenko, Olga Melnik, Liudmyla Voloshyna This paper proposes an economical thermal cycle of the production of ceramic articles from submicronic powders of aluminum oxide, titanium oxide, and manganese oxide. The implementation of a given cycle involves the introduction of a special aluminophosphate bond into the charge in order to reduce […]
