Development of a Computational Method for Prediction of After-Burning Effect

This proposal is being submitted in response to the solicitation topic N10A-T002 (Development of a Computational Method for Prediction of After Burning Effect) by BUSA Engineering Consulting (Dr. Jianghui Chao) in collaboration with University of Florida (PI: Prof. S. Balachandar). The overall objective of the proposed effort is to contribute to national defense and security by advancing the state of the art in computational prediction of after-burning munitions. We propose to replace current empiricism by developing fundamental physics-based models of explosive driven dispersal of particles and droplets and their subsequent after-burn. The work plan for Phase I and Phase I option is assess the existing force, heat transfer and burn-rate models with focused attention to the problem of after-burn explosives/fuels and prepare the ground work needed to develop, validate and demonstrate advanced physics-based models and to integrate them in a versatile computational framework.
