Abstract. Recent experimental studies on muzzle blast overpressure histories of an
81mm mortar system have revealed a number of reproducible features
following the main blast front. Some of these features are
shock fronted, with pressure rizes of similar magnitude to that
in the main blast front. The time lapse indicates that
these may be associated with the precise geometry of the
projectile. A study was therefore undertaken, using our previously validated
computational fluid dynamics (CFD) code, to examine the evolution of
the flowfield behind the blast front. The primary concern is
to achieve an improved understanding of the changing flowfield, and
how this determines the features of the experimentally measured pressure
history in an 81 mm mortar.
