Jet formation experiments and computations with a Lagrange code

摘要

A jet formation routine has been generated that can be used with (Lagrange) explosive cone‐collapse calculations. It calculates the velocities of jet and slug elements, as well as their mass, formation point, and time. The equations and method of operation are presented here. Experimental jet velocities agree with the model to 10. Jet deformation calculations required yield strengths up to 24 kbar to yield agreement with experiments on copper jets.
