Abstract : Two methods were used to introduce a projectile into the flow field from the muzzle of a 5 inch/54 gun. The first method employed a barrel fixed coordinate system, the second employed a projectile fixed coordinate system. Calculations were made using both methods for a 5 inch/54 gun blast, and the results were compared. The blast field without a projectile present was also calculated. All Calculations were carried out using a version of the one-material axisymmetric SHELLTC hydrodynamic code using a digital computer. (Modified author abstract)
