Computational Equipment for Support of Air Force Sponsored Programs for the Design of Advanced and Miniaturized Explosive and Advanced Propellant Systems
Abstract
This grant funded the acquisition of a 128 node/256 processor cluster computer that now supports the computational needs of the combined, Air Force-sponsored research groups of Prof. D. Scott Stewart (PI) in Mechanical Science and Engineering, (MechSE), Prof. John Buckmaster (Co-PI) in Aerospace Engineering (AE), and Thomas L. Jackson (Co-PI) in Computational Science and Engineering (CSE), all at the University of Illinois. The combined Stewart/Buckmaster/Jackson group continues to support advanced explosive system design and advanced propellant combustion and addresses critical areas needed for advanced high energy density devices central to the AF's mission. Stewart is currently supported by grants from AFRL Munitions Directorate and AFOSR/ Physical Mathematics and Applied Analysis (AFOSR/NE). Buckmaster and Jackson are supported independently by AFOSR/NE. Stewart's group in Mechanical Science and Engineering (MechSE) uses the equipment to carryout research simulations to model critical scientific experiments related to explosives devices of interest to the Munitions Directorate, (AFRL/RW), Eglin AFB, such as adaptable munitions, miniature and micro-munitions efforts and other new systems, in collaboration with AFRL/RW and other designated research teams. The simulations of shock and detonation physics are fully three dimensional (3D), multi-scale, multi-phase, involve high-pressure, highdensity multi-material interactions, and require facilities to carry out large-scale calculations. The Buckmaster/Jackson group are engaged in carrying out large-scale, 3D, multi-material simulations of low Mach number burning of heterogeneous propellants of current interest to AFRL's Propulsion Directorate, Space and Missile Propulsion Division and AF supported contractors. These simulations require long term averaging of the burning of propellant beds and need computations on a fast, parallel computational platform with rapid turnaround for optimization.
