Liquid injection inlet particle separator systems and methods

An inlet particle separator system for a vehicle engine, comprising:

• a separator assembly defining an inlet flow path for receiving inlet air, the separator assembly including a scavenge flow path and an engine flow path downstream of the inlet flow path, the separator assembly configured to separate the inlet air into scavenge air and engine air such that the scavenge air is directed from the inlet flow path into the scavenge flow path and the engine air is directed from the inlet flow path into the engine flow path;
• a liquid injection system coupled to the separator assembly and comprising a nozzle configured to introduce a diffused liquid into the inlet air flowing through the separator assembly;
• and
• an electrohydrodynamic (EHD) assembly coupled to the separator assembly and configured to direct the scavenge air into the collector assembly.
