Hydrodynamic characteristics of the proposed dish of cage


Amplitude ratio of 7 Conclusion (1) under the action of the pure flow velocity greater the greater the force. Cage dive dish suffered for reducing flow of power to be little effect. (2) pure waves,[link widoczny dla zalogowanych], the force cage size and wave height is proportional to the relationship with the cycle is not obvious. Cage dive dish suffered for reducing wave forces to be better results. (3) The combined effect of wave and current, whether floating or submerged state of the state, after the cages are flow greater than the force of pure wave under the same stress wave conditions. Combination of floating down the river when the waves and the force when the anchor rope is less than the wave and counter combination. After the combination of diving when the wave with the cable upstream power may be rather large when compared with floating. Thus ability to increase the cage against the joint effect of the storm, whether the dive cage to be dish should be carefully handled. (4) Net flow cages under the force is proportional to its maximum displacement. Pure waves,[link widoczny dla zalogowanych], dive for the effect of significantly reducing the amplitude. Combined effects of the pure wave and wave and current, the amplitude and the wave height is essentially proportional relationship between the obvious and period. (5) is the volume of the proposed dish dish cage cages 2.03 times the force of pure countercurrent flow and when combined with large waves, and the remaining cases, the increase of the force not to dish cages 2 times. From the perspective of movement amplitude, to be dished cages in most cases are smaller than the amplitude of the dish network box, when the combined effect of wave and current after the dive under the cage of the amplitude ratio of the proposed dish dish network box amplitude is somewhat larger,[link widoczny dla zalogowanych], but the maximum is also 1.36 times. Therefore, compared with the disc cage, the application to be dished cage deserves attention. References [1] Guifu Kun, Zhang Huaihui. Project Development and Prospect of cage [J].
