Scaling of Water Flows and Obstacle Displacements in Shallow Underwater Explosion Field Tests

Abstract

This work develops a theory for scaling fluid and underwater obstacle motion caused by shallow explosive charges. The motivation is to be able to replicate full-scale test results in subscale experiments despite the fact that gravity remains the same in both tests. The scaling theory is based on the incompressible Euler equations and results for fluid motion are verified through computational example. The applicability of this scaling to obstacle motion is demonstrated by comparing full and subscale obstacle displacement data.
