Comparison of TDNOVA Results with an Analytic Solution.

Abstract

Presently, two-dimensional, two-phase interior ballistic computer codes are being developed. One such code is TDNOVA. In this report, numerical simulations of TDNOVA are compared to an analytic solution of a one-dimensional problem in order to provide some checks on the accuracy and the cost of running the code. The problem considers the propellant completely burned at time-zero and was solved analytically by Love and Pidduck. The differences between the analytic solution and TDNOVA are on the order of 0.1% for pressure, velocity, distances, and time. The calculations cost as little as $1.00 for a complete solution, requiring 2.27 cp seconds execution time on a CDC 7600 computer system.
