Inlet particle separators only prevent 60-70% of fine dust particles (1-80 μm) from entering the core flow of the turbine engine. Therefore, operation of helicopters in dusty environments can cause significant damage to different sections of the turbine engines due to ingestion of fine dust particles. In this work, electrostatic enhancement of IPS performance was demonstrated for a vaneless ...

ELECTROSTATIC SEPARATION
Electrostatic separation is done by initially charging the particulates or contaminants and then moving and concentrating them at the electric field boundary. Electrical separation was first demonstrated by Hohlfield in 1824 by clearing a smoked-filled jar with an electrified point. In 1884, Oliver Lodge attempted to collect lead fume using an ...
