Abstract

See full text

A swirling flow generator for gas-liquid separation includes a swirling flow generating ribbon for swirling a gas-liquid two-phase fluid flowing through a pipe to guide a liquid toward an inner surface of the pipe by centrifugal force. A terminal end of the swirling flow generating ribbon where the gas-liquid two-phase fluid is to flow out includes a first terminal edge and a second terminal edge. The first and second terminal edges connect a first terminal end point, a second terminal end point, and a middle terminal end point. The first terminal end point is in a first of radially outward ends and the second terminal end point is in a second of the radially outward ends. The middle terminal end point is closer to a side where the gas-liquid two-phase fluid is to flow in than the first and second terminal end points and is on an axial line.
