Thermodynamics and hydrodynamics of spontaneous and forced imbibition in conical capillaries: A theoretical study of conical liquid diode
Masao Iwamatsu
Thermodynamics and hydrodynamics of spontaneous and forced imbibition of liquid into conical capillaries are studied to assess the feasibility of a conical liquid diode. The analyt…
Free-energy landscapes of intrusion and extrusion of liquid in truncated and inverted truncated conical pores: implications to the Cassie-Baxter to Wenzel transition
Masao Iwamatsu
As the simplest model of transition between the superhydrophobic Cassie-Baxter (CB) and Wenzel (W) states of a macroscopic droplet sitting on a microscopically rough or corrugated…
Effect of line tension on axisymmetric nanoscale capillary bridges at the liquid-vapor equilibrium
Masao Iwamatsu, Hiroyuki Mori
The effect of line tension on the axisymmetric nanoscale capillary bridge between two identical substrates with convex, concave and flat geometry at the liquid-vapor equilibrium is…
Four stages of droplet spreading on a spherical substrate and in a spherical cavity -Surface tension vs line tension and viscous dissipation vs frictional dissipation-
Masao Iwamatsu
The spreading of a cap-shaped spherical droplet of non-Newtonian power-law liquids on a completely wettable spherical substrate is theoretically studied. Both convex spherical subs…
A generalized Young's equation to bridge a gap between the experimentally measured and the theoretically calculated line tensions
Masao Iwamatsu
A generalized Young's equation, which takes into account two corrections to the line tension by the curvature dependence of the liquid-vapor surface tension and by the contact angl…
Topography- and topology-driven spreading of non-Newtonian power-law liquids on a flat and a spherical substrate
Masao Iwamatsu
The spreading of a cap-shaped spherical droplet of non-Newtonian power-law liquids on a flat and a spherical rough and textured substrate is theoretically studied in the capillary-…
