2023, International Journal of Thermal SciencesCitation Excerpt :For example, in the space environment, the temperature range is very large, which can vary from −100 °C to 200 °C, and the temperature gradient could change direction or even be omnidirectional. The existence of temperature gradient causes the liquid lubricants to migrate on the mechanical components surfaces, which could seriously affect the lubrication effect and even lead to the failure of lubrication [15]. Thus, it is very practical to study the omnidirectional migration of droplets, especially on the hydrophilic surfaces due to the lubricating properties, which can help to understand and control the lubrication.

2021, Tribology InternationalCitation Excerpt :As a liquid droplet is exposed to a thermal gradient, the molecules tend to move to the cold side, enhancing the migration [32–34]. Investigations reported by Khonsari and Fusaro [35,36], Jones et al. [37], Zaretsky [38], and Wang et al. [39] revealed that increasing the viscosity or surface tension of liquids or decreasing the thermal gradient can weaken the migration behavior to some extent. Dai et al. [40] carried out a systematic study to gain insight into the migration capacity of different lubricants on different surfaces.
