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

Heat Transfer, EarlyView.
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 ...

Experimental Investigation of Sub-Cooled Flow Boiling in Metallic Microchannel [PDF]

Engineering and Technology Journal, 2019
Experiments in microchannel heat sink were carried that examine the deionized water two-phase boiling heat transfer. The heat sink consisted of a single microchannel having 300μm wide nominal dimensions and 300μm height (hydraulic diameter of 300μm). The

Phase appearance or disappearance in two-phase flows [PDF]

, 2011
This paper is devoted to the treatment of specific numerical problems which appear when phase appearance or disappearance occurs in models of two-phase flows. Such models have crucial importance in many industrial areas such as nuclear power plant safety

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review

Heat Transfer, EarlyView.
ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that

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 ...

Heat-transfer characteristics of screw tube in one-side high heat load condition for fusion reactor divertor application

International Journal of Advanced Nuclear Reactor Design and Technology, 2021
In this study, the heat transfer characteristics of one-side heated screw tubes were analyzed using subcooled flow boiling experiments. The experiments were performed until the critical heat flux was reached, while the applied heat flux was gradually ...

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.
