Original Abstract

The phase change materials (PCMs) represent thermal storage materials that have become widely used in many engineering applications. The PCMs, which can change the phase within the range of operational conditions, allow for storage and consequent release of a large amount of energy due to the latent heat of the phase change. One of the possible applications of PCMs is the attenuation of temperature fluctuations in the applications with the demand on the temperature stability. The investigation of thermal behavior and optimal design of water-PCM attenuator is dealt with in the paper. A numerical model of heat and mass transfer in a circular attenuator was developed in MATLAB with the effective heat capacity method used to address the phase change. The square wave character of the inlet temperature fluctuation was considered. The nature-inspired heuristic firefly algorithm, which utilizes the developed numerical model as a black-box, was implemented for the optimization.
