摘要
基于流动显示及模拟实验结果,本文分析了波浪场中,水底圆管周围的流场状况;提出了级数式升力计算模式;研究分析了升力系数C_(L(n)),随KC数的变化规律;最终通过实例,验证了该计算模式的可靠性,并给出了可供工程实际应用的某些参数。
Based upon the flow surveillance and results of simulated tests, the article analyzes the status of wave flowing field around subsea pipe in the wave field.The article puts forward series in calculation modes for lifting force and it also presents a study on the changeable rules of lifting force coeffcient Cu(n) which varies with KC. At the last, by means of actual exam-ples, the reliability is verified and some parameters used in the practical engineering are provided.
