一、前言我所最近新建的循环水槽,为船舶水动力试验提供了新的测试环境,它与通常采用的拖曳水槽的不同点是被试验物体固定不动,水在循环槽中按不同的速率运动,对被测试物体进行多种试验。当前,世界各国对循环水槽的功能评价很高,在循环水槽中可进行船舶阻力,推进、操纵,海洋构造物及渔捞工具等许多流体力学问题的研究,由于具备试验过程的可观测性及水流速度对时间系列的稳定性等优点,有些测试工作是静水水槽无法替代的。我所自循环水槽建成以来,不断扩大其应用范围,除了完成船模试验中的有关流体力学问题的
I. INTRODUCTION The new circulating water tank newly provided by our institute provides a new test environment for the hydrodynamic test of ships. The difference between it and the commonly used tow tank is that the tested object is stationary, and the water is circulated at different rates Exercise, the object under test for a variety of tests. At present, many countries in the world have highly evaluated the function of circulating water tank. Many research on hydrodynamics problems such as ship resistance, propulsion, maneuver, marine structure and fishing gear can be carried out in circulating water tank. Due to the observability of the test process and Water flow rate on the stability of the time series, etc., some of the test work is still water tank can not be replaced. Since the completion of the circulation tank, I have been expanding its range of applications. In addition to completing the hydrodynamics problems in the ship model tests
