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.

Heat Transfer Coefficient Determination during FC-72 Flow in a Minichannel Heat Sink Using the Trefftz Functions and ADINA Software

Energies, 2020
This work focuses on subcooled boiling heat transfer during flow in a minichannel heat sink with three or five minichannels of 1 mm depth. The heated element for FC-72 flowing along the minichannels was a thin foil of which temperature on the outer ...

Effect of substrate thermal resistance on space-domain microchannel [PDF]

, 2009
In recent years, Fluorescent Melting Curve Analysis (FMCA) has become an almost ubiquitous feature of commercial quantitative PCR (qPCR) thermal cyclers. Here a micro-fluidic device is presented capable of performing FMCA within a microchannel.

Analysis of State‐of‐Health Estimation Approaches and Constraints for Lithium‐Ion Batteries in Electric Vehicles

International Journal of Energy Research, Volume 2024, Issue 1, 2024.
Energy storage systems (ESS) are seeing rapid market growth due to the changing worldwide landscape of electricity distribution and consumption. An ESS must possess the capability to oversee the functioning of the system’s modules under abnormal circumstances, while also having the ability to supervise, manage, and optimize the performance of one or ...

The effect of tube diameter on vertical two-phase flow regimes in small tubes [PDF]

, 2006
Flow boiling flow patterns in four circular tubes with internal diameters of 1.10, 2.01, 2.88 and 4.26 mm were investigated in the present project. The experiments were conducted in vertical upward two-phase flow using R134a as the working fluid.
