Some Topics and Future Prospect on “Interfacial Flow and Wetting”

(Personal Beginnings of Wetting Study and Community)

Abstract

Dynamic wetting / dewetting, which is characterized by the motion of the contact line (the triple phase line of the liquid-fluid interface and the solid surface), is ubiquitously-observed phenomenon in two- or three- phase flow field confined by solid walls. The behavior of the contact line and the contact angle is one of the major boundary conditions for the description of the behavior of the bulk interface, understanding of the behaviors are hence highly required. In this article, recent topics and future prospect on the interfacial flow and wetting are briefly introduced, with some personal histories of the authors’ studies on that field.
