| 摘要 |
The present invention relates to a flow form to be used in gaseous or liquid moving fluids, comprising a leading edge (4) defining a dividing line for the flowing medium, two opposite lying surfaces (6, 7) along which the medium flows over the flow form, and a downstream end behind which the medium divided by the flow form converges once again. In order to provide a flow form with enhanced energy utilization and/or energy conversion when compared with known flow forms, and which exhibits specially lower flow losses, the invention proposes that the downstream end should consist of an end section (3) which can be elastically folded around a theoretical axis running almost perpendicular to the direction of flow and lying parallel to a surface defined by the leading edge (4) and the direction of flow, wherein the flexibility of the end section (3) is a multiple of that of the main part (2) of the flow form (1) lying in front of the end section (3) in the direction of flow. |
