Consider a free boundary problem of compressible-incompressible two-phase flows with surface tension and phase transition in bounded domains Ωt+,Ωt−⊂RN, N≥2, where the domains are separated by a sharp compact interface Γt⊂RN−1. We prove a global in time unique existence theorem for such free boundary problem under the assumption that the initial data are sufficiently small and the initial domain of the incompressible fluid is close to a ball. In particular, we obtain the solution in the maximal Lp−Lq-regularity class with 2<p<∞ and N<q<∞ and exponential stability of the corresponding analytic semigroup on the infinite time interval.

In this paper we consider a hyperbolic free boundary problem describing a pressure-controlled flow of a Bingham-like fluid in a channel. The free boundary is the surface that separates the inner core (where the velocity is uniform) from the outer layer, where the fluid behaves like the upper convective Maxwell fluid. First, the problem is reduced to an equivalent system of equations of the first order, which allows us to study the behavior of the free boundary in the considered time interval and establish the global solvability of the problem

A free boundary problem that arises from the physical phenomenon of "peeling a thin tape from a domain" is treated. In this phenomenon, the movement of the tape is governed by a hyperbolic equation and is affected by the peeling front. We are interested in the behavior of the peeling front, especially, the phenomenon of self-excitation vibration. In the present paper, a mathematical model of this phenomenon is proposed. The cause of this vibration is discussed in terms of adhesion.
