摘要

对纳米气泡的研究主要集中在除鳞和稳定性方面，对其传热性能及其影响因素的研究较少。目前还缺乏一个全面的理论框架。本研究建立了一个模拟电厂循环冷却水过程的实验平台。结合实验数据和分子动力学模拟，系统地研究了纳米气泡在不同水类型和pH环境下的传热效应。研究发现，纳米气泡在pH值为7-8的河水中传热效果最佳。

Influence of fluid composition on heat transfer characteristics of nanobubbles: Experimental and simulation insights

Research on nanobubbles has mainly centered on descaling and stability, with limited attention to their heat transfer performance and influencing factors. A comprehensive theoretical framework is still lacking. In this study, an experimental platform was developed to simulate the circulating cooling water process in a power plant. The heat transfer effects of nanobubbles were systematically examined across various water types and pH environments, combining experimental data with molecular dynamics simulations. The study found that nanobubbles achieved optimal heat transfer in river water at a pH of 7–8.

期刊介绍： The International Journal of Thermal Sciences is a journal devoted to the publication of fundamental studies on the physics of transfer processes in general, with an emphasis on thermal aspects and also applied research on various processes, energy systems and the environment. Articles are published in English and French, and are subject to peer review. The fundamental subjects considered within the scope of the journal are: * Heat and relevant mass transfer at all scales (nano, micro and macro) and in all types of material (heterogeneous, composites, biological,...) and fluid flow * Forced, natural or mixed convection in reactive or non-reactive media * Single or multi–phase fluid flow with or without phase change * Near–and far–field radiative heat transfer * Combined modes of heat transfer in complex systems (for example, plasmas, biological, geological,...) * Multiscale modelling The applied research topics include: * Heat exchangers, heat pipes, cooling processes * Transport phenomena taking place in industrial processes (chemical, food and agricultural, metallurgical, space and aeronautical, automobile industries) * Nano–and micro–technology for energy, space, biosystems and devices * Heat transport analysis in advanced systems * Impact of energy–related processes on environment, and emerging energy systems The study of thermophysical properties of materials and fluids, thermal measurement techniques, inverse methods, and the developments of experimental methods are within the scope of the International Journal of Thermal Sciences which also covers the modelling, and numerical methods applied to thermal transfer.
