Helical flow turbine for producing and using helical fluid flows, has helical channel wound around axis of turbine, and provided with openings
摘要
<p>The turbine comprises a helical channel (3) with a round cross-section. The channel winds at least once around the axis of the turbine (2) and comprises one or more openings (4) on the rotation axis side or tangentially. The openings are preferably dimensioned so that the lateral fluid inflow into the helical channel allows the formation of secondary helical flows in the helical channel cross-section.</p>
