【Abstract】 A pendulous device is used to simulate oscillating flow. The flnid dynamic coefficients of circular cylinders with small tubes are measured in the flow. The C D and C m of a single smooth circular cylinder, which is taken as the checking model, are measured and compared with the data in references to verify the test method. Systemic measurement for circular cylinders with one, two or three tubes are carried out. valued data are obtained, which may be refered to in the design of ocean mining equipment.更多还原
