One-Dimensional Analysis of a Radial Source Flow of Water Particles into a Vacuum

Abstract

An analytical investigation is made of a one-dimensional radial source flow of water into a vacuum. The equations that describe this model are a sixth-order, nonlinear, two-point boundary value problem. The problem is solved by the shooting/splitting technique. The results of this investigation are compared with the other works in the literature and the comparisons generally are in good agreement. Engineering parameters for the release of water into space are used to give some indication of waterflow characteristics into a vacuum environment; these parameters were chosen to resemble those of a recent water release experiment from the space shuttle. Keywords: Flow models, Water release, Space physics, Particle temperature, Particle size, Particle freezing, Vapor pressure, Particle velocity.
