A study on the behavior of an underwater explosion bubble near a gid all

Abstract EN

The dynamic approach to an underwater explosion (UNDEX) is a complex episode that involves shockwave propagation, bubble pulse with high pressure, and water jet impact.

this paper proposes linkage of finite element avenue (FEM) and companion of eulerian-lagrangian (CEL) to supply promised data of large deformations and flow simulation of fluid and gas where the bubble interaction is near a stiff wall.

to conduct the process, a 7.5 m x 9.0 m Eulerian domain and explosive charges of 10 g, 35 g and 55 g TNT are built in a free field, respectively.

numerical analysis, as far as a comparison with research from e.

klaseboer, has been given in this study.

the important results obtained from the CEL approach imply high expectations.

in spite of the fact that this approach is not adequately consistent to totally supplant a live test, it can be utilized as an outline database to anticipate outcomes of managing an UNDEX with a high pressure bubble.

the behavioral explosion from an UNDEX bubble near a rigid wall is a prospective contribution in this research.

With these results, this technique can be used in further studies to examine UNDEX bubbles in the vicinity of deformable and complex structures.
