The wave problem is predicted by adopting panel method based on kelvin source for a ship traveling in a uniform flow 摘要采用基于开尔文源的面元法求解航行于均匀流场中的船舶兴波问题。
Now , most of the design of the sewage is according to gravity flow and we looks on the flow as water flow 目前的污水管道设计大多按重力流考虑,认为其流动状态为均匀流,与清水在明渠中的流动类似。
In this thesis , the steady performance of ducted propeller in uniform flow is predicted by surface panel method 本文应用基于扰动速度势的低阶面元法,拟计算导管螺旋桨在均匀流场中的定常水动力性能。
This technique can effectively improve the cavitation performance and resolve the design problem of propeller operating in unsteady flow field 能有效地改善非均匀流场中螺旋桨的空泡性能。解决了非均匀流场中螺旋桨设计问题。
Sewage pipe flow is hypothesized as single - phase and uniform flow , and we are used to applying the chezy formulas for designing sewer systems 目前的污水管道设计是将污水在管道内的流动视为单相均匀流,主要用谢才( chezy )公式进行水力计算。
