This paper investigates the complex mechanism involved in the solid-nanofluid-oil interactions by directly observing the phenomenon of nanoparticle self-layering due to confinement of nanoparticles in a thin film. This research also shows that the effect of film size on stability of nanolfluid films on a solid substrate.
In this paper, the experimental results of the nanoparticle self-ordering and stepwise thinning of the nanofluid film fromed between an oil drop and a solid surface are reported. This also presents the measured contact angle of film-meniscus and thickness corresponding to the number of particle layers on a solid surface. These were used for getting the film energy due to the nanoparticle layering within the nanofluid film.
