摘要： PURPOSE:To improve diffuser efficiency in such a way that an optionally shaped substance is installed in the diffuser flow path on the downstream side which is lower than the position in which the expansion ratio is to be a specific value so that part of the sectional area is closed at its position. CONSTITUTION:In case where a flat plate M which is the simplest shape as an obstacle is installed on one-sided opening quadratic diffuser, the diffuser inlet port width is assumed as B0, the diffuser height constantly assumed as H, and the expension ratio assumed as 4.2. Therefore, the flat plate M whose height is assumed as H, width assumed 0.5B0, and thickness assumed as 0.1B0 in the diffuser is fixed by just one as the obstacle in the flow path. When they are selected within (a)-(e) at the setting position of M, efficiency is improved by increasing the pressure recovery rate Cp at the outlet port of the diffuser.

摘要： PURPOSE: To prevent separation from occurring because the flow of fluid along a wall surface changes the proceeding direction along the wall surface, by providing a locally accelerating protrusion at the separation point on an inside boundary wall.
CONSTITUTION: A locally accelerating protrusion 3, whose outline is smooth and whose upstream part as to the direction of flow of fluid projects sharply to the flow, is provided on at a separation point on an inside boundary wall 2. At a point II of the distribution of velocity of the fluid flow in the presence of the protrusion 3, the fluid flow near the wall 2 is sharply accelerated in a short section by the protrusion 3 so that the velocity u
1 near the protrusion 3 is especially heightened. An effect similar to what is called Coanda effect can be produced by changing the direction of the flow after especially increasing the momentum of the portion with the velocity u
1 . For that reason, the direction of the flow can be changed while holding the pressure loss down and preventing separation, without disturbing the flow and using a separate motive power source.

摘要翻译：目的：为了防止分离，因为流体沿着墙壁表面的流动沿壁面改变行进方向，通过在内侧边界壁上的分离点处设置局部加速的突起。构成：在内侧边界壁2上的分离点处设置有轮廓平滑的局部加速突起3，并且流体的流动方向的上游部分突出地突出地流向流动。在点II处在存在突起3的情况下流体流速的分布，靠近壁2的流体流在突出部3的短截面中急剧加速，使得突起3附近的速度u1特别提高。通过改变流速的方向，可以通过改变速度u1的部分的动量来增加类似于所谓的柯达效应的效果。因此，可以在保持压力损失并防止分离的同时改变流动方向，而不会干扰流动并使用单独的动力源。

摘要： PURPOSE:To increase a deflection angle width (swing width), by a method wherein second connection ports to the air and closing plates for the connection port are mounted, and when the first connection ports to the air are closed, the other second connection ports are opened. CONSTITUTION:Second connection ports 16R and 16L to the air are positioned at the sides of control ports 3R and 3L, and second closing plates 14R and 14L for communicating port to the air are provided. The second connection ports are designed to open and close according to the displacement of transmission members 13R and 13L. When a communicating port 9L to the air for control is closed, the second communicating port 16R is opened through the transmission member 13R, and the inside of the control port 3R becomes an atmospheric pressure, meanwhile, the inside of the other control port 3L becomes a negative pressure. This increases a differential pressure between the right and left control ports 3R and 3L, whereby, through the rotation of a closing plate 10' for the first connection port, and efficient swing action takes place in a state holding a proportion property, and air-conditioning range is enlarged.
