摘要
本文应用N—S方程式,导出了压力和连续方程的解析式,求解了水流参数的半数值半解析的精确解.其结果表明,精确的理论解和一般的势流理论解的流场计算结果相差很大.本文对前人的试验研究中提出的关于出口断面水流内部是否存在负压问题进行了探讨.本文给出的理论分析结果和实测结果吻合得较好.
Semi-analytical solutions of N-S equations and continuity are given out in this paper. The results reveal that, the accurate analytical solution as quite different from that of the conventional potential flow. Some researchers observed negative pressure in the brink section, others did not in their experiments. The reason for the inconsistency is discussed, in detail The results of the theoretical solutions appear to be generally in agreement with experimental data.
