Numerical Diagnostics of Shaped Charge Jet Structure and Formation from a Liner Driven by Products of Detonation
Journal Title: PROBLEMY TECHNIKI UZBROJENIA - Year 2018, Vol 148, Issue 4
Abstract
The paper describes the known processes of collapsing of shaped charge conical liner elements to the axis of symmetry and their partition into an internal part creating the jet and an external part remaining in the slug. An element of the liner has the length of a numerical cell and is divided into 18 layers perpendicularly to the liner contour. The existence of velocity gradients along some liner elements creating the jet is shown – the first internal layers of liner elements get the maximal velocities. In consequence the shaped charge jet has a layered structure which is similar to a shaped charge jet produced by half-spherical liner. Axial homogeneity of the jet is a function of liner material granulation and numerical cells dimensions in our case. Results of numerical calculations are compared with results of analytical calculations based on the PER model.<br/><br/>
