The present invention relates to an apparatus to uniformize flow of circulation water for air trapping, installed in a front end of a tunnel observation part to observe supercavitation of an underwater body, and to uniformize flow of water supplied from the tunnel observation part. According to the present invention, the apparatus comprises: an inlet expansion pipe part having an inlet to circulate and inject water drained from the tunnel observation part, and extended from the inlet to have a diameter gradually increased when compared with a diameter of the inlet; a body part having the same diameter as the largest diameter of the inlet expansion pipe part, and extended from the inlet expansion pipe part; and an outlet reduced pipe part extended from the body part to have a diameter gradually decreased when compared with the diameter of the body part and connected to the tunnel observation part. According to the present invention, as the circulated water is reduced through the inlet expansion pipe part and an identical flow rate is formed in accordance with a depth from the body part, formation of turbulence of the water supplied to the tunnel observation part is minimized; thus stabilizing flow of the circulation water flowing in the tunnel observation part.

    본 발명 공기포집을 위한 순환수 유동 균일화 장치는, 수중체의 초월 캐비테이션을 관측하기 위한 터널 관측부 전단에 위치되고, 터널 관측부로 유입되는 물의 유동을 균일하게 하는 공기포집을 위한 순환수 유동 균일화 장치에 있어서, 터널 관측부로부터 배출된 물이 순환하여 주입되는 입구가 형성되고, 입구의 직경에 비하여 점차적으로 큰 직경을 갖도록 입구로부터 연장된 유입확관부와, 유입확관부의 가장 큰 직경과 동일한 직경을 가지며 유입확관부로부터 연장된 몸체부와, 몸체부의 직경에 비하여 점차적으로 작은 직경을 갖도록 몸체부로부터 연장되고 터널 관측부와 연결된 배출축관부를 포함하며, 순환하는 물이 유입확관부를 통해 감소되고, 몸체부에서 깊이에 따라 동일한 유속을 이루게 되므로, 터널 관측부로 유입되는 물의 난류 형성이 최소화됨으로써, 터널 관측부에 유동하는 순환수의 유동이 안정화되는 효과가 있는 공기포집을 위한 순환수 유동 균일화 장치를 제공한다.
