Summary on Grant Application Form
Simulation of rarefied gas dynamics requires solution of the Boltzmann Equation. For engineering applications this necessitates numerical solution. In the past Direct Simulation Monte Carlo (DSMC) modelling using Cray vector processing has been adopted. It is now recognised that such architectures have limited potential for further expansion in terms of cost effectiveness. It therefore proposed to develop a DSMC code to run within a parallel processing environment. Thus the objectives are: (1) to improve and enhance the modelling capabilities of rarefied gas flows by developing a simulation code to be run on a massively parallel computer. (2) To develop novel, portable algorithms and applicable tools for this type of simulation which would also be applicable to other simulation problems. (3) As a test case, the 'shuttle glow' phenomenon will be investigated. An engineering tool able to predict the radiation, arising from the interaction between a satellite in low earth orbit and ambient atmospheric species will be developed. Such radiation can contaminate sensitive space instrumentation, including earth observation sensors. This will enable the spacecraft configuration design to be assessed for the first time, computers such as the MasPar and the Parsys Supernode available within the London Parallel Application Centre.
