Soft Matter and Complex Systems Seminar

In the presentation I will discuss the problem of interaction between a gas-liquid interface and a small object moving in its vicinity. In particular, I will present the concept of a wave resistance, which is an important quantity in a number of macroscopic systems. On the other hand, on a microscale, deformation of a gas-liquid interface caused by a moving object can be relevant for a capillary bridge formation. I will discuss this problem in the context of relevant length and time scales, which play a crucial role in the description of the dynamic deformation of a gas-liquid interface.
