Coanda spiral flow is completely different from the conventional flow or turbulent flow, which is known as the concept of fluid motion.
This was discovered by the inventor of the present invention as something that is different from turbulent flow even though it is under a fluid motion condition that belongs to a turbulent flow region. Its generation has already been proposed by this inventor.

In other words, the inventor of this invention discovered that when a vector in the radial direction of the pipe is added to the vector of fluid in the direction of the pipe, the fluid is twisted, a dynamic boundary layer is formed near the inner wall of the pipe based on this swirling flow, and the fluid is caused to spiral. We discovered the fact that it moves at high speed in the direction of the pipe while drawing a spiral. In such a Coanda spiral flow, the fluid moves at high speed, and due to the presence of a dynamic boundary layer, even if solid particles are present, they do not collide with the inner wall of the pipe as in the case of turbulent flow. During the process of the fluid's spiral motion, the state of the fluid is maintained uniformly, and local deterioration due to collision or contact with the inner wall is suppressed.
