Numerical simulation study of composite solid propellant small scale gap test

Integrated Simulation of Solid Propellant Rockets

This paper presents an overview of research activities at the Center for Simulation of Advanced Rockets (CSAR) at the University of Illinois at Urbana-Champaign. CSAR is one of five university-based research centers funded by the U. S. Department of Energy as part of the Accelerated Strategic Computing Initiative (ASCI). The purpose of ASCI is to advance the state of the art in computational si...

HTPB-Polyurethane: A Versatile Fuel Binder for Composite Solid Propellant

ARDEC Solid Gun Propellant Shock Initiation Sensitivity Test

NOL large card gap test is not suitable to assess the shock sensitivity of granular propellant beds made of large grains. The result can be strongly influenced by the heterogeneity of the bed. A new small scale gun propellant shock sensitivity test has been developed at ARDEC. This test is a sensitive discriminator to assess gun propellant shock sensitivity. INTRODUCTION Shock-to-detonation sen...

Numerical Simulation of Wave Overtopping Over Composite Berm Breakwater

Breakwaters have changed a lot during their design history. Overtopping is an important parameter that its evaluation and reduction has always been noticed. In this study, the wave overtopping of composite berm breakwater as a new conceptual structure has been investigated numerical modeling was performed using FLOW-3D software. Then, based on  a laboratory model conducted by Losada et al, cali...
