Special Issue Information

Dear Colleagues,

“Energy systems” encompass all the thermodynamic systems in which heat or mass transfer occurs. These systems implicate a huge number of phenomena and applications, from the ground to outer space. In order to focus the contents of this Special Issue, we aim to explore topics covering the successful implementation of recently advanced and innovative numerical and analytical modeling techniques. These methods could have a substantial impact on the comprehension and virtual reproducibility of physical phenomena, supporting an increase in industrial system performance and thermal efficiency. I invite all colleagues and scientists working in the field of thermo-fluid dynamics and thermal sciences to submit a paper with at last two of the following three main characteristics: (1) inspiring or offering a better explanation of physical processes, (2) having a clear link to a high-impact and novel application, and (3) containing an original advancement in terms of numerical modeling or methods.

Prof. Dr. Marco Marengo
Guest Editor

Power electronics convert and control electrical power in applications ranging from electric motors to telecommunications and computing. Ongoing efforts to miniaturize these systems and boost power density demand advanced thermal management solutions to maintain optimal cooling and temperature control. Spray cooling offers an effective means of removing high heat fluxes and keeping power electronics within safe operating temperatures. This study presents an experimental investigation of flash spray cooling in a closed-loop system using R410A refrigerant. In particular, two nozzles with different spraying angles are used to study the effects of the distance between the spray nozzle and a heated flat surface, as well as the mass flow rate of the coolant. Results indicate that three key flow-pattern factors—surface coverage, impingement intensity, and liquid film dynamics—govern the heat transfer mechanisms and determine cooling efficiency. Flash spray cooling using refrigerants like R410A demonstrates strong potential as a high-performance thermal management strategy for next-generation power electronics. Full article

This study explores the impact of using water-Al2O3 nanofluids, at different nanoparticle concentrations, in solar thermal collectors for solar cooling applications. Improving the seasonal energy performance of solar cooling systems is a current research priority, and this work investigates whether nanofluids can significantly enhance system efficiency compared to traditional heat transfer fluids. A transient simulation was carried out using a dynamic model developed in TRNSYS (TRANsient SYstem Simulation), evaluating the system performance throughout the cooling season. The results show that in July, under low volumetric flow conditions and with nanoparticle concentrations of 0.6% and 0.3%, the solar fraction reaches a maximum value of 1. Using a nanofluid at 0.6% concentration leads to significantly higher fractional energy savings compared to pure water. Despite increased pumping energy, the overall energy savings—which include the contribution from an auxiliary boiler—exceed 80% when nanofluids are used. This study goes beyond previous work by providing a dynamic, system-level simulation of nanofluid-enhanced solar cooling performance under realistic operating conditions. The findings demonstrate the practical potential of nanofluids as a valid and more energy-efficient alternative in solar thermal applications. Full article
