Abstract
This paper has the objective of developing a numerical simulation of a solid-fluid interaction using the commercial software Abaqus®. A Coupled Eulerian-Lagrangian (CEL) analysis will be used to understand the entrance of a solid object in a fluid surface. The 3D model will include a chamfered cylinder of lead (projectile) with initial velocity and a static rectangular fluid body. From this paper, relevant information and steps of CEL analysis will be learned, as defining material parameters, creating appropriate mesh, applying initial condition, fluid-structure interaction and, finally, extracting data from the software. The main goal of this work is the development of a low cost ballistic projectile recovery chamber project. The authors intend to use the density and viscosity capability of some fluids to stop ballistic projectile without damaging it. Therefore, understanding the impact between the solid and the fluid and the influence of density and viscosity in this process is primordial. In this final paper is expected to see some difference in the depth penetration of the projectile when the density and viscosity of the fluid is changed. It is expected that increasing density and viscosity values will reduce the penetration depth of the projectile and also increase how fast the projectile reduce its velocity.
