APPARATUS AND METHOD FOR OSCILLATING FLUID JETS

摘要

A method of causing a fluid flow to oscillate between two exit directions. The method comprises causing a primary flow of fluid though a conduit (330), the conduit (338) characterized by two exit directions (350,360) and providing first and second oscillation control ports (340), said first and second oscillation control ports transverse to said conduit and connected to one another by a feedback tube (440).
