A continuum method for modeling surface tension
TL;DR: In this paper, a force density proportional to the surface curvature of constant color is defined at each point in the transition region; this force-density is normalized in such a way that the conventional description of surface tension on an interface is recovered when the ratio of local transition-reion thickness to local curvature radius approaches zero.

An investigation of particle trajectories in two-phase flow systems
S. A. Morsi,A. J. Alexander +1 more
TL;DR: In this article, the authors describe a theoretical investigation into the response of a spherical particle to a one-dimensional fluid flow, and the motion of the spherical particle in a uniform 2D fluid flow about a circular cylinder.

Mathematical Basis and Validation of the Full Cavitation Model
TL;DR: In this paper, the authors present the full cavitation model, which accounts for all the first-order effects of cavitation and is called as the full-cavitation model and the phase change rate expressions are derived from a reduced form of Rayleigh-Plesset equation for bubble dynamics.
