Investigation of Inertial Particle Separator Geometry for Helicopter Engines
Objective Test a 2D IPS geometry that
separates particle flow from airflow.
Design IPS Geometry is a flow splitter
design with a core region for airflow and a scavenge region for sand flow.
Senior Project | Aerospace Engineering | May 2018
Methods Sand particle behavior was categorized through shape
characterizations which was done with use of a profilometer and particle imaging software. 2D
airflow through the IPS geometry was simulated by Computational
Fluid Dynamics (CFD) with ANSYS Fluent.
Results
Findings • 2D CFD validates efficacy of
90% airflow through core and 10% airflow through scavenge
• Changes in splitter geometry affect size of recirculation zone
Introduction Helicopters operating in the desert
ingest sand into their engines damaging them and decreasing their
longevity. An Inertial Particle Separator (IPS) may mitigate this
problem.
