Use of the Naval Hydrocode Gemini to Simulate In-Air Explosions and Predict Shock Conditions in Field Fortifications
Abstract
This paper presents results from a research and development effort directed toward the enhancement of warfighter capability to perform rapid vulnerability assessments of blast effects (from threats such as car bombs) on field fortifications. This is a capability that does not currently exist in the warfighters toolkit, and is considered to be of tremendous relevance based on the current operational environment and common mode of enemy attack. The approach to development of this capability is based on use of a first-principles hydrocode as a virtual test bed to perform large numbers of shock effects calculations on an expedient protective structure. The hydrocode data is then used to build a statistically generated response surface, which can be implemented in easy-to-use warfighter assessment tools. As an added benefit of this effort, the hydrocode Gemini was used to perform simulations. This code has been primarily developed for use in underwater explosion applications, but is expected to also accurately perform in-air detonation calculations. Therefore, calculational results benchmarked against experimental data provide information that supports expansion of code use to other applications of Army interest.
