讲座内容：
Among the most difficult issues in CFD is the very wide range of scales involved in some problems. Attempts at investigating the contact line problem have been made coming from various theoretical and numerical frameworks, the closest to first principles being molecular dynamics, while diffuse interface methods and sharp interface methods with several variants have also been put forward. Experiments are obviously difficult. Efforts were made on a number of typical cases, including plunging and withdrawing plates, a sheared droplet, sessile droplets on oscillating or accelerating substrates, menisci in nanopores and the hydrodynamics assist problem. The issues involved in nucleate boiling and accelerated sessile droplets will be addressed both from the point of view of experiments (performed by various colleagues from MIT and Tokyo University) and from the point of view of simulations.
