激流回旋航道中不同挑角丁坝附近流场水位的计算

Calculation on water heights near typical obstacle in channel of Slalom Kayaking

皮划艇激流回旋航道产生激流的主要方法之一是在航道上不同地方安放不同大小、不同角度的丁坝,从而形成复杂的水流。因此,对丁坝绕流的研究是激流回旋运动重要的基础性研究。运用计算流体力学FLUENT软件,对4种挑角的丁坝附近水流场的水位进行了数值计算,总结速度的变化特点和一般规律,为皮划艇激流回旋运动技术提供理论上的支持,为运动员改进和完善运动技术提供科学依据。

The method of making torrents was to fix the different angles of groins in ditterent areas and different speciation, thus it could form the complicated currents, Therefore, research on the flows of the groins was the basic research to the velocities of the current fields of Slalom Kayaking. Using the FLUENT software of fluid dynamics computation, the water heights around these different angles of groins was computed. The characteristics of the variation and the general rules were summarized, which could provide the theoretical supports for the skill of Slalom Kayaking.
