Research on water-entry impact and flow-fluid characteristics of tangent ogive structure

摘要

Authors of this paper are preceding the water-entry processes of three tangent ogives structures with different velocities and water-entry angles, based on moving grid technique and numerical simulation of two-phase model. Through analyzing the results of simulation, the load peak value influences are revealed when several ogives enter water with different velocities and water-entry angles. From the simulation, it can be concluded that the 30° tangent ogive does well on the axis performance and the 90° tangent ogive shows more stability on radial direction.
