Method for circulating fluids, such as solid- or biological components, involves producing vertical circulating flow, particularly oscillating and directional circulating flow, by resonant vibration of fluid

摘要

The fluid circulation method involves producing a vertical circulating flow, particularly an oscillating and directional circulating flow, by a resonant vibration of a fluid. A gas cushion (3) is located above the fluid in a pipe (1,2), where the volume of the pipe is periodically changed by a vibration drive (4), particularly with a sinusoidal waveform. A pulsed effective downward flow is generated in an annular gap between two pipes that are concentrically attached to each other. An independent claim is included for a device for carrying out the fluid circulation method in large vessels, tanks or standing water.
