Název v původním jazyce

Oil-well Perforator, Lagrangian and Eulerian LS-DYNA Simulations

Popis výsledku v původním jazyce

Fast dynamics of an oil-well perforator was numerically simulated by using 3D LS-DYNA, Version 970, code covering explosive detonation, liner collapse and jet formation. Two different numerical approaches were used: Lagrangian and Eulerian numerical simulations. The Lagrangian simulations confirmed that the element distortion problems are very significant and the liner jet non-regular mesh in time could cause that the jet formation would not be correct. Moreover, it was observed that the perforator liner should had to be divided at least into approximately ten elements across the liner thickness in order to obtain quasi real jet parameters. The second Eulerian analysis demonstrated that this approach is more stable and could give useful information about the jet properties: for example its geometry, velocity, and density. The results obtained will be used in the consecutive future analysis regarding the jet penetration effects on surrounding materials, usually steel tube and rocks or c
