Keywords: nonisothermal microscale systems, moving fluid, interfaces


In many nonisothermal microscale systems moving fluid interfaces come into apparent contact with confining solid walls, forming the so-called apparent contact lines. Their dynamics is determined by a complex interplay between viscous flow, evaporation, surface tension, and disjoining pressure effects. Both global shapes of fluid interfaces and the parameters of heat transfer in typical microscale systems depend on the local phenomena taking place near apparent contact lines. Recent progress in mathematical modeling of apparent contact lines will be discussed in the talk, including comparisons with experiments, molecular dynamics simulations, and new applications related to nanotechnology.
