摘要
现有二元滑行理论建立在单驻点流动模型的基础上,作者在二元滑行面上布置汇来模拟抽吸,提出一种有汇滑行面双驻点的流动模型。利用复变函数理论推导出一组流体力学基本方程组,从原则上解决了有抽吸情况下滑行面的理论计算问题。对于现有的二元滑行理论这是一种扩充。作者所进行的二元滑行艇的强迫滑行和自由滑行试验,以及有20°横向斜升角的V-形艇自由滑行试验都表明,抽吸可以有效地减少喷溅。
The current two dimensions planing theory is based on the flow model with one standing point.In this article we use a sink placcd on the planing surface to model the suction and give a new flow model with two standing points for planing surface with a sink.A group of basic fluid mechanic equations are developed by using the theory of function of complex variable.The equations can in principle solve the theoretical calculation problems for planing surface With a sink.It is a development to current two—dimensions planing theory.It is.shown from the experiments of free-planing and forced-planing for twodimensions planing craft and from the experimet of V-shaped prismatic surfaces having angies of 20°,that the suction can effectively decrease the spray.
