Laminar boundary flow control device for turbulent gas flow e.g. for heat exchanger or electrofilter, uses adjustable piston for providing shock variation in flow velocity in laminar boundary layer

摘要

The laminar boundary flow control device provides a shock alteration in the flow velocity within the laminar boundary layer, using a piston (3) displaced within a cylinder (4) via drive magnets (2), to provide alternating pressure variations, or oscillating movement of a gas quantity regulation flap.
