Abstract
Nanobubbles are ubiquitous but invisible. Neither a single nanobubble nor billions of nanobubbles are easy to study. However, reports on positive benefits of nanobubbles in everyday life are numerous and seem to increase by the day. There seems to be a significant gap between everyday usage and firm scientific understanding of nanobubble behavior. The authors were interested in conducting simple fluid dynamic experiments that are often used in textbooks to challenge how the inclusion of nanobubbles may alter commonly accepted findings. This approach led us to discover that nanobubbles can be an entirely new, inexpensive, and environmentally friendly modifier of flow behavior. This paper is a start of our efforts and reports our preliminary results on nanobubbles as a friction modifier.
期刊介绍：
Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International.
Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
