An Inlet Particle Separator Design System

Development of a three-dimensional p article trajectory analysis for inlet particle separators is proposed by combining a continuum flow Navier-Stokes analysis capable of simulating flow in an installed inlet with a three-dimensional Lagrangian based particle tracking analysis. Both components represent state-of-the-art technology and their combination would provide a much improved approach capable of integration into aircraft engine design systems. The procedure's capabilities would be extended through incorporation of a stochastic wall reflection model and a particle shattering model. Phase I would combine the two components, add a shattering capability and run a demonstration calculation. Phase II would focus upon further verification via a combination of computation and experiment and model modification and improvement based upon the experimental/computational studies. In addition, Phase II would provide for ease of use of the computational procedure in the design process by structuring a Graphical User Interface (GUI) both for problem setup and output interrogation.
