Effect of polyethylene glycol and activated carbon macroparticles on thermal conductivity of paraffin wax for thermal storage applications

Low thermal conductivity is the major obstacle for the wide range utilization of phase change materials (PCMs), especially organic PCMs, for most practical applications in thermal engineering. This study investigates the potential of enhancing the charging and discharging rates of organic PCM (RT44H...
