Project start: 1.10.2025.

Research on the project is focused on increasing the efficiency of heat exchange in green energy systems. The project activities include experimental measurements on the fin and tube heat exchangers and on the latent heat storage as well as the analyses of the results obtained from experimental research. For selected types of heat exchangers and heat storage, the physical problems of heat exchange will be described, appropriate mathematical models will be defined, numerical procedures will be selected and validations will be carried out by comparing numerical results with the results of experimental measurements performed on established test lines for heat exchangers and latent heat storage. Throughout the numerical research, a series of computational simulations will be carried out for various geometry characteristics and operating conditions of the heat exchangers and heat storage, using experimentally validated numerical models. Parametric analyses of the influence of geometry characteristics and operating conditions on heat exchange and efficiency will be performed. Also, optimization procedures of the influencing parameters will be carried out in order to find their optimal values with the aim of increasing the efficiency of heat exchange in green energy systems. The objective of the research is to improve the heat exchange efficiency in renewable energy systems contributing to the green transition. The project objectives include improving heat exchange by optimizing the geometry characteristics and operating conditions of fin and tube heat exchangers, as well as increasing the efficiency of green energy storage by optimizing the geometry and operating parameters of the latent heat storage. The expected scientific contribution of the research includes the development, validation and application of advanced computational tools for performing thermodynamic analyses and optimization procedures of heat exchange and heat storage components in green energy systems, contributing to the green transition, energy saving and sustainable development.
