Electron-Molecule Collisions and UV Signatures in Flowfields

Abstract

The high-performance, cost-effective computing provided by massively parallel computers can be expected to have a significant impact on our ability to simulate complex physical and engineering systems. Such capabilities will strengthen the competitiveness of U.S. defense and commercial industries. However, robust simulations of systems such as flowfields over hardbodies and plumes must increasingly rely on an adequate data base for the fundamental chemical and physical processes occurring in these systems. Much of this data base is either unavailable or experimentally inaccessible. The use of parallel computers in these studies of electron collisions with molecules for modelling of flowfields is an early example of the significant role that scalable high- performance computing can play in meeting such data-base needs for several defense and dual-use applications. With the projected scaling of these machines to much larger numbers of microprocessors and improvements in hardware and algorithms, performance levels well in excess of that achieved on the early versions of the machines used in these studies can be expected. In summary, these machines will certainly have a revolutionary impact on our ability to model complex systems.
