![]() Such near-critical fluids are investigated both from a fundamental and from a practical point of view. For example, the specific heat of such fluids tends to infinity, which has the potential of a breakthrough in the thermal energy storage area. Fluids near their critical point (NC-fluids: near-critical fluids) possess extraordinary properties. Additionally, the group researches nano-PCMs where small quantities of nano-additives can considerably affect relevant properties of PCMs such as temperature and enthalpy of phase transition, specific heat, thermal conductivity, hysteresis, etc. For this reason, the development of shape-stabilized PCMs by advanced encapsulation, coating, and impregnation methods, as well as exploration of solid-solid phase transitions, are among the main activities of the group. Despite many advantages of PCMs like high energy density and near isothermal charge-discharge, the leakage problem is a severe engineering limitation. The development of such kind of smart PCMs is among the interests of the group. However, designing PCMs so that the phase transitions can also be driven by other types of external stimuli (e.g., electric, magnetic and electromagnetic fields, mechanical stimuli) is of great interest because this provides the PCM with additional functionalities (e.g., heat transportation, heat pumping) and helps to solve some of the current problems of PCMs (e.g., subcooling, poor heat transfer ability). ![]() Phase transitions in PCMs for TES are determined by temperature. Smart external-stimuli responsive PCMs.Some of the active topics of the group include: The final goal of the group is to deliver attractive solutions for the industry by overcoming material science challenges. This involves new materials design and synthesis, full characterization, materials optimization, and life-time analysis. The group is dedicated to the study of phase change materials (PCMs) as well as critical phenomena for the benefit of thermal energy storage (TES) and thermal management applications. ![]()
