    Abstract

    It was claimed by Dussan [J. Fluid Mech. 75, 609 (1976)] that in order for a bounding surface not to be a material surface either the speed of propagation of the surface is not equal to the normal speed of the particle situate upon it or more than one deformation can be associated with the velocity field. These conditions are shown to be insufficient through examples drawn from the theory of dynamical systems which also suggests the correct way to separate a bounding surface from a material surface.
