Particle Dynamics Simulation for Aeroengine Intake Design
Abstract
The design of an engine intake comprising an inertial inlet particle separator is accomplished under this work. With that purpose a Navier Stokes solver is used for aerodynamics performance investigation for design and off design conditions and the particle trajectories are obtained using a post process tool. In order to obtain the particle trajectories the equations of particle dynamics are integrated following an explicit scheme. The time step limitations of the explicit method depending on the particle size and Reynolds number are discussed and some details of the methodology followed to integrate the equations on the discredited domain are given. Finally, aerodynamics results of the intake are shown and the particle trajectories for a wide range of particles sizes are obtained in order to assess the separation efficiency of the intake system.
