On the Design of Recuperator for Transcritical Cycle Adopting CO2‐Based Mixture as Working Fluid: A Focus on Transport Properties Prediction

Energy Technology, Volume 12, Issue 1, January 2024.
CO2 binary mixtures in transcritical power cycles offer efficiency improvements compared to sCO2 in hot‐environments, but no studies on transport properties are available for complex/asymmetric CO2 mixtures. This work proves that the friction theory model, calibrated on pure component data, has superior predictivity compared to traditional models.

Effects of Elastic Walls on the Thermal Performance of a Counterflow Heat Exchanger

International Journal of Energy Research, Volume 2024, Issue 1, 2024.
Using elastic plates in combination with counterflow heat exchangers is an innovative aspect of thermal energy storage systems (TES). The incorporation of elastic plates dramatically enhances heat transfer. However, prior studies have yet to thoroughly investigate the effects of exerting force on these elastic plates.
