NOVA Code Simulation of a 155-mm Howitzer: An Update

Abstract

The NOVA two-phase flow interior ballistic code was employed to simulate ignition, flamespreading, and pressurization in a 155-mm Howitzer. For these calculations, all input data were independently determined, and comparison was made between predicted results and experimental data. Good agreement between theory and experiment was shown to exist for overall pressurization profiles and, in one case, for pressure waves themselves. However, experienced ignition delays were grossly underpredicted, suggesting several specific limitations to the model.
