下图是一种新型的急流导向鼻坎——曲面贴角鼻坎。曲面贴角体与底平面交线半径为r、园心角为β″的园弧线,随高度的增加,则平行于鼻坎底的任一弧长逐渐减短,直至边墙顶为零,贴角曲面体的末端边墙为一斜率λ_s 线,贴体是凹边墙的一部分。设计中利用不同参数的组合(R/λ、β″/θ、B/h 等参数),使其适应急流在凹岸的流动和导向控制。利用凸边墙的扩散或收缩来调整凹凸岸两股水流冲击、交汇的发生点,促使水舌在纵向得到充分的
The following figure is a new type of jet-oriented nasal ridge - curved nose paste nose corner. Curved corner of the body and the bottom plane intersection radius r, central angle β “Park arc, with the height increases, then parallel to the bottom of any length of the arc gradually reduce the arc until the top of the wall is zero , The corner wall of the body is a slope of the slope line λ_s line, body is concave wall part of the design of the use of different combinations of parameters (R / λ, β ”/ θ, B / h and other parameters) Adapt to the flow and guidance control of rapids in the concave bank. The use of the convex wall of the proliferation or contraction to adjust the bump shore two water impact, the intersection point of occurrence, prompting the water tongue in the vertical sufficient
