Abstract:

This report describes an extension to TDNOVA, a code whose purpose is the digital simulation of convective flamespreading through bagged artillery charges. TDNOVA is based on the numerical solution of the axisymmetric, two- dimensional equations which govern the macroscopic aspects of the flow of a two- phase, heterogeneous mixture. Of principal interest are the inter-play among the venting characteristics of the ignition system, the properties of the bag and the distribution of ullage during the period of flamespreading, and the consequences of the path of flamespreading in respect to the structure of the longitudinal pressure field throughout the entire interior ballistic cycle.
