Opportunity Description

Numerical Modeling of Reacting Multidimensional Gas/Solid Flows Advisor: Nusca, Michael J. [Click Here To Join]; 410.278.6108) Key words: Fluid Dynamics, Particle Dynamics, Numerical Simulation, Solid Propellant, Reacting Flow, Turbulence This opportunity involves the development and application of computational fluid dynamics (CFD) codes that solve the multiphase, three-dimensional, Navier-Stokes equations for chemically reacting gases and burning solid particles. Applications include flows in which all or some of the following effects are important: solid propellant combustion, gas-phase combustion (including hypergolic), equilibrium and finite-rate chemical kinetics, radiation, diffusion, turbulence, vorticity, liquid droplet combustion, porosity, and compaction. Emphasis is placed on performing original research, model generation, and solving practical problems such as those encountered in modeling solid propellant gun charges (interior ballistics) and solid propellant rocket engines (internal ballistics) for next-generation missile systems. We encourage the development of original CFD codes as well as the use of COTS codes. Computer resources include PC and LINUX workstations, as well as SGI, IBM, and CRAY mainframes. ARL is the site of one of the DOD's Major Shared Resource Centers for high-performance computing. This vast array of computing resources makes the performance of complex CFD simulations feasible. Publications in the open literature and the presentation of papers at appropriate technical meetings and conferences are encouraged. This Research Opportunity aligns with the ARL Sciences for Lethality and Protection Campaign: Ballistics and Blast, in the area of Weapons and Energy Projection.

About Us

Oak Ridge Associated Universities (ORAU) administers Science, Technology, Engineering and Mathematics (STEM) research participation programs for civilians such as:

The U.S. Army Research Laboratory (ARL) Research Associateship Program (RAP) allow Postdoctoral Fellows, Journeyman Fellows (undergraduate and graduates students and recent graduates), Senior Researchers, and Summer Faculty engage in research initiatives of their own choice, that are compatible with the interests of the government and will potentially contribute to the general effort of the ARL. Scientists and engineers at ARL help shape and execute the Army's program for meeting the challenge of developing technologies that will support Army forces in meeting future operational needs.

Research opportunities include, but are not limited to the following disciplines: Aerospace Engineering, Anthropology, Archeology, Biology, Biochemistry, Biological Engineering, Biomechanical Engineering, Biomedical Engineering, Chemical Engineering, Chemistry, Computer Science, Computer Engineering, Electrical Engineering, Environmental Health Risk Assessment, Environmental Science, Entomology, Epidemiology, Ergonomics, Geology, Health Education Mechanical Engineering, Materials Science, Mathematics, Nanotechnology, Photonics, Physics, Public Health Economics, Public Health Policy, and more.
