海洋工程水池潮流发生装置—特殊轴流泵的水力设计及流动计算

Hydrodynamic Design and Flow Calculation of Specific Axial Pump for Current Generator of Offshore Engineering Model Basin

随着海洋工程的发展,许多国家已建造模拟真实海况潮流现象的水池。本文研究了海洋工程潮流发生装置——特殊轴流泵系统,对这种低扬程、极高比转数的特殊轴流泵进行了水力设计。理论分析了转轮内部流动,建立了用有限元方法进行流动计算的计算机程序。在对日本平冢研究所试验水池的轴流泵(ns=2250)作校核设计的基础上,给出了新的设计条件下(ns=1580)算例的数值结果。

In this paper, the hydrodynamic design scheme of a specific axial pump with high ns for the current generator of the offshore engineering model basin is presented. A computer program is performed for the calculation of the flow within the pump by finite element method. Based on a numerical design scheme of the axial pump model (ns = 2256) from Japan, new design model (ns = 1580) is presented.
