Heat Transfer Performance of Biphilic Surfaces With Diatomite‐Based Composite Coatings in a Closed Thermosyphon System

Heat Transfer, Volume 55, Issue 3, Page 1608-1638, May 2026.
ABSTRACT This study investigates the thermal performance of innovative biphilic boiling surfaces designed for CPU cooling applications using a two‐phase closed thermosyphon (TPCT) system. The surfaces were fabricated by applying composite coatings—comprising epoxy resin and diatomite particles functionalized with APTES and PFOTS silanes— onto Al1050 ...

Investigation of Wall Boiling Closure, Momentum Closure and Population Balance Models for Refrigerant Gas–Liquid Subcooled Boiling Flow in a Vertical Pipe Using a Two-Fluid Eulerian CFD Model

Energies
The precise design of heat exchangers in automobile air conditioning systems for more sustainable electric vehicles requires an enhanced assessment of CFD mechanistic models for the subcooled boiling flow of pure eco-friendly refrigerant.

Performance Investigation of Eco‐Friendly Refrigerant Mixtures as an Alternative to R134a in Vapour‐Compression Refrigeration System

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 2, March/April 2026.
ABSTRACT The growing impacts of climate change and energy scarcity demand environmentally sustainable refrigeration solutions. This study investigates eco‐friendly refrigerants (R152a, R290 and R600a) and their optimized ternary mixture as alternatives to R134a. Four blend compositions were analysed using experimental testing and REFPROP 10.0 modelling

Seismo‐Acoustic Evidence for Meteoric Water Modulation of Hydrothermal Fluid Discharge

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Deciphering the signal of external processes on active hydrothermal dynamics represents a critical challenge in understanding volcanic unrest. At the Pisciarelli hydrothermal site, located within the densely populated Campi Flegrei caldera (Italy), we investigate the role of meteoric water influx in modulating shallow hydrothermal fluid ...

An experimental investigation of void fraction characteristics of flow boiling in a 5×5 rod bundle channel

Case Studies in Thermal Engineering
Flow boiling in the rod bundle channel is an important phenomenon in nuclear reactors. The local inhomogeneous void fraction distribution in the flow channel will affect the flow and heat transfer in two phase flow.

Effect of inlet subcooling on flow boiling in microchannels

Applied Thermal Engineering, 2020
Abstract The paper describes experimental work to assess the effect of inlet subcooling on the flow boiling characteristics of HFE-7200 in a multi-microchannel heat sink. The experiments were performed at a mass flux of 200 kg/m2 s and system pressure of 1 bar for inlet subcooling conditions of 5 K, 10 K and 20 K and wall heat flux between 25.9 and ...

A Model‐Based Interpretation for the Apparently Homogeneous Steam Bubble Nucleation in Industrial Evaporative Sucrose Crystallization

Journal of Food Process Engineering, Volume 49, Issue 3, March 2026.
A model has been developed and validated with data from the sugar industry to determine the evaporation rate of discontinuous evaporating crystallizers. The results indicate that vapor nucleation on the surface of sucrose crystals is a significant factor, particularly in the context of low temperature differences in the calandria.
