Description

Jig for fixing the upper position and adjusting the height of the experimental model for the two-dimensional blue reproduction tank {UPPER PART FIXING AND VERTICAL HEIGHT ADJUSTMENT JIG FOR EXPERIMENTAL MODEL IN TWO DIMENSIONAL WAVE FLUME}

The present invention relates to an upper position fixing and height adjustment jig for an experimental model for a two-dimensional wave reproduction tank, and more particularly, for vertical adjustment of a sensing unit that senses the impact of waves generated in a two-dimensional water tank, position measurement and vertical adjustment It relates to a jig for fixing the upper position and adjusting the height of the experimental model for a two-dimensional wave reproduction tank having a vertical movement unit.

Recently, as interest in the ocean, such as offshore plants and marine energy, has increased, the need for wave channel experiments is increasing, and accordingly, experimental research related to ships, offshore plants, and wave power generation, etc., is being conducted a lot in Korea.

Most of the wave-related experiments target a 2D simple wave or a 3D irregular wave generated by superimposing various simple waves.

Since the two-dimensional tank is small, easy to operate and can generate relatively accurate waves, it plays an important role in basic research on wave characteristics or experimental research on the interaction between waves and objects.

However, since the length or width of the two-dimensional tank is generally limited, the characteristics of the generated wave should be carefully examined in advance.

On the other hand, the generation of waves in the two-dimensional water tank is made through a wave maker, and there are piston, flap, plunger, cylinder types, etc., among them The flap-type wave generator has a simple structure and is easy to control to generate a desired wave, so it is widely used in 2D and 3D water tanks.

For piston-type or flap-type wave breaker, there are linear wave breaker theory based on linear theory and second-order non-linear theory, and research on plunger type has been conducted.

Although waves are generated in a two-dimensional tank based on this theory, the characteristics of the actually generated waves vary depending on the type of wave generator, the specifications of the wave tank, and the performance of the wave wave device. In order to perform this, a device suitable for wave generation characteristics in a two-dimensional tank is required.
