Experimental Investigation of Capillary-Driven Two-Phase Flow in Water/Butanol under Reduced Gravity Conditions

Study on the instability of FC-72 vapor-liquid interface in a rectangular channel under different gravity conditions

“…Barrett [17] analyzed moving contact line dynamics during droplet evaporation in a vapor bubble experimental setup, considering capillarity, viscous flow, and disjoining pressure effects with neglect of gravity, and employing a two-component model to describe disjoining pressure, with direct comparisons to experimental receding contact line dynamics in a quartz cuvette with n-butanol. Cecere [18] studied capillary flow of water/butanol mixtures in a single groove heat pipe model, revealing their enhanced stability and higher dry-out limit compared to pure water due to anomalous surface tension behavior with temperature. Chen [19] utilized drop tower experiments to study deflector transfer speed in plate-type surface tension tanks, a second-generation design known for its simple structure, easy processing, and high reliability, representing the future direction of such tanks, with corresponding numerical simulations conducted in Fluent using the VOF method.…”

Thermal performance of self-rewetting gold nanofluids: Application to two-phase heat transfer devices

“…In the literature, many efforts have been devoted to study the influence of different types of working fluids such as nanofluids and binary mixture fluids (called as self-rewetting fluids) on heat transfer systems performance. So, these fluids were proposed for the first time by Abe and Savino [25][26][27]. Savino et al [28] investigated experimentally and numerically the thermal performance of self-rewetting fluids in an innovative heat pipes.…”
