NUMERICAL SIMULATION OF AN UNDERWATER EXPLOSION BY SPH METHOD

Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2016, Vol 61, Issue 1

Abstract

This paper presents theoretical and practical fundamentals regarding numerical analysis of an underwater explosion. Its parameters and effects upon submerged structures represent the aim of the numerical analysis by Smoothed Particles Hydrodynamics (SPH). SPH method is a version of a more general numerical method, named free particle method. The fundamentals of explosion theory and of the SPH method are supposed to be known, so this paper intends to present only the particularities of an underwater explosion and how its parameters and effects can be modeled by SPH method. The example finishing the paper represents an available numerical model for such problems.
