Heat Transfer. 2013;135(6): doi: / Figure Legend: Evaporation sequence of liquid film of argon on Pt wall in the Y-Z plane along the computational domain. The liquid film does not completely evaporate and a nonevaporating film is obtained [58].

Heat Transfer. 2013;135(6): doi: / Figure Legend: (a) 3D view of MD simulation domain of thin liquid argon films in a nanochannel. Vapor pressure-density plot of initial and final states for (b) varying nanochannel height, and (c) varying film thickness. Initial and final vapor states lie on the saturation curve [57].

From: Fundamental Roles of Nonevaporating Film and Ultrahigh Heat Flux Associated With Nanoscale Meniscus Evaporation in Nucleate Boiling J. Heat Transfer. 2013;135(6): doi: / Figure Legend: Simultaneous evaporation of argon thin film on nanochannel upper wall with condensation on the lower wall. (a) Variation of the vapor pressure with time, and (b) snapshots of the domain at different time steps. Nonevaporating film does not form on the upper wall since the vapor pressure reduces due to vapor condensation [57].

Heat Transfer. 2013;135(6): doi: / Figure Legend: Liquid argon meniscus, surrounded by argon vapor, in an opening constructed of platinum wall atoms. (a) 3D view of the simulation domain where the liquid-vapor interface can be clearly noticeable, and (a) 2D view along the x-z plane depicting the boundary conditions and dimensions. Heat is transferred to the meniscus from the platinum wall region shown in red, while the region shown in blue is maintained at the lower initial temperature [80].

From: Fundamental Roles of Nonevaporating Film and Ultrahigh Heat Flux Associated With Nanoscale Meniscus Evaporation in Nucleate Boiling J. Heat Transfer. 2013;135(6): doi: / Figure Legend: Variation in liquid pressure along the meniscus at t = 2500 ps for the nanoscale meniscus. High negative pressure values are seen at the center of the meniscus. A normalized function log(Π/δne) is plotted in the region of negative liquid pressure for Π=RC=-2γ/PL and Π=δ(x), which nullifies the possibility of cavitation in this region as the meniscus thickness is smaller than the critical cavitation radius [90].
