摘要

液滴在液体电绝缘中的行为，特别是变压器油，在损耗和电强度方面是必不可少的。前人对水滴在交流电场中的变形进行了实验研究，本文对这些实验进行了扩展，使用了各种油和先进的设备，具有更高的时空分辨率。此外，还进行了数值模拟，以更深入地了解所调查的过程。实验和模拟结果表明，变形和电压之间存在相位延迟

Water droplet deformation at alternating electric field action: experiment and numerical simulation

The behavior water droplets in liquid electrical insulation, specifically transformer oil, is essential in context of losses and electrical strength. Experimental studies on water droplet deformation in an AC electric field have been conducted previously, and this paper expands on those experiments using various oils and advanced equipment with higher spatiotemporal resolution. Furthermore, numerical simulations were performed to gain deeper insights into the processes under investigation. In result, the experiments and simulations revealed a phase delay between deformation and voltage

期刊介绍： Interfacial Phenomena and Heat Transfer aims to serve as a forum to advance understanding of fundamental and applied areas on interfacial phenomena, fluid flow, and heat transfer through interdisciplinary research. The special feature of the Journal is to highlight multi-scale phenomena involved in physical and/or chemical behaviors in the context of both classical and new unsolved problems of thermal physics, fluid mechanics, and interfacial phenomena. This goal is fulfilled by publishing novel research on experimental, theoretical and computational methods, assigning priority to comprehensive works covering at least two of the above three approaches. The scope of the Journal covers interdisciplinary areas of physics of fluids, heat and mass transfer, physical chemistry and engineering in macro-, meso-, micro-, and nano-scale. As such review papers, full-length articles and short communications are sought on the following areas: intense heat and mass transfer systems; flows in channels and complex fluid systems; physics of contact line, wetting and thermocapillary flows; instabilities and flow patterns; two-phase systems behavior including films, drops, rivulets, spray, jets, and bubbles; phase change phenomena such as boiling, evaporation, condensation and solidification; multi-scaled textured, soft or heterogeneous surfaces; and gravity dependent phenomena, e.g. processes in micro- and hyper-gravity. The Journal may also consider significant contributions related to the development of innovative experimental techniques, and instrumentation demonstrating advancement of science in the focus areas of this journal.
