The debris simulation tool will offer a powerful simulation capability of first order importance to the Space Exploration Program for robotic and human mission architecture definition to the Moon, Mars, and other destinations. The highest risks occurring during propulsive landing and takeoff of spacecraft require gas-granular flow simulation capabilities for designing mitigation measures. The granular flow modeling capability will be equally important for modeling regolith material manipulation for In-situ Resource Utilization such as pneumatic transport, granular flow movement in excavators, resource extraction systems moving and conveying regolith, as well as processing of regolith in reactors for resource extraction.
Many potential non-NASA commercial applications exist in civil and military industries. Multiphase flows occur in many applications in chemical, petro-chemical, energy conversion, mining and pharmaceutical industry. Industrial practitioners are well aware of the huge role particle shape plays in the flow behavior of real particulate systems. Understanding and accurately modeling such flows would lead to greatly improved designs of multiphase flow reactors. Dust, sand and snow stir-up during helicopter landing and take-off in a desert or arctic environment result in severe visibility impairment (brown-out) and danger of engine debris ingestion. Civil engineering and environmental engineering applications include wind-borne landscape erosion and dust transport to populated areas.
