| 内容記述 | The upwelling current brings up nutrient-rich water from subsurface towards sea surface. If a plenty of nutrient are supplied into the euphotic zone, the primary productivity will be increased there by enhancement of photosynthesis. As a result of a food chain, the upwelling region becomes an area of higher fishery production. In order to generate the upwelling artificially, various shapes of marine structures installed on the seabed are studied so far. The present paper describes the results of flow visualization carried out for models of marine structures which generate upwelling effectively. The shapes of marine structure used in the experiments are a triangle cylinder like mountain range, a vertical wall, V-shaped structure and various combination of two V-shaped structures, such as X-shaped, W-shaped and so on. Flow visualization tests were carried out in a small towing tank whose dimensions are 4m long, 0.5m wide and 0.4m deep. The carriage runs on the bottom of the tank with constant speed by use of towing wire. The malachite green of basic dyes was used as a tracer. The height of models used is 3cm and the speed of carriage is 0.05m/s, and then Reynolds number was about 1350. It is found that if the subsurface current flows in one way direction, V-shaped structure induces the most effective upwelling. On the other hand, X-shaped structure generates upwelling effectively in all directions of current. |
