“…The first, more complicated approach, is based on conservation laws, expressed as differential equations, augmented by empirical relationships for friction, heat transfer, and propellant ignition and combustion [Kuo (1977); Takata and Wiedermann (1976); Kuo (1973); Krier and Gokhale (1976)]. …”

“…The Illinois model has been documented in three articles 6,7,8 which describe the approach and some results; the coding has not been published. Of note are the diffusion terms in the momentum and energy equations, the use of a solid phase energy equation, the bulk temperature ignition concept, and the treatment of the gas phase pressure gradient.…”

Code predictions were compared with firing test values and with a lumped parameter code. Quantitative comparisons are reported for pressure difference waves, peak breech pressure, rise time and travel at peak pressure, flame spreading rate, and CPU time. The major findings were that (1) each code predicts different pressure DO 1 JAM 73 1^73 EDITION OF I NOV 65 IS OBSOLETE UNCLASSIFIED SECURITY CLASSIFICATION OF THIS PAGE (Whan Data Entered) UNCLASSIFIED SECURITY CLASSIFICATION OF THIS PAGEfWInn Dmf Bntertd) waves, (2) pressure wave predictions are insensitive to the presence of the central core igniter, and (3) nominal data are inadequate for quantitative predictions.

“…It is a onedimensional model, in which the powder particles are considered to be fixed in space. More elaborate one-dimensional models, which include the motion of solid particles, have subsequently been proposed Van Tassel and Krier 1975;Krier and Gokhale 1976;Gough and Zwarts 1979;Kuo et al 1976;Chen et al 1981;Koo 1975), the latter being an extension of the KVS model. However, certain phenomena, recognized as being relevant to the interior ballistics of guns, cannot be explained by means of a one-dimensional description.…”

Abstract. An axisymmetric viscous two-phase model is presented which describes the transient combustion of granular propellants during the ignition phase of a ballistic charge. Details of the model are presented along with computational results for a low-pressure ballistic simulator. Predicted pressure time evolutions are compared with experimental data of a real test-firing in which an unexpected pressure excursion occurred. Gun propellant breakup effects, due to bed compaction, are taken into consideration to explain the discrepancies between the numerical and experimental results. Finally, a discussion is presented of the mechanisms by which the behavior of pressure waves can be strongly intluenced and thus controlled by the manner in which the propelling charge is ignited.
