An Evaluation of the ALPHA Code in Its One-Phase Mode.

Abstract

The initial validation program for ALPHA, a new, state-of-the-art, transient, two-phase, two-dimensional algorithm for interior ballistics calculations is presented. The verification of the simulation of the ballistic cycle for a simplified gun, the Lagrange gun, is made by comparing the computed results with the analytical solution for the core flow and by testing the consistency of the numerical results. The ALPHA simulation of the two-dimensional, one-phase flow in the Lagrange gun is shown to be more accurate than previous calculations.
