    • PROBLEM TO BE SOLVED: To provide a seeding device capable of minimizing ratio of tracer particles with large diameters which contaminate a wind tunnel.SOLUTION: When tracer particles are injected into a hood 12 together with air from a nozzle 16 of a seeder 13, the air is guided by a collision surface 12e of the hood 12 and deflects to downstream direction of the air flow inside a wind tunnel and flows out into the wind tunnel via an opening 12d of the hood 12. Tracer particles having large diameters are not forced to flow with the deflected air because of their great inertia. Rather, they move straight and collide with the collision surface 12e and are captured there, thereby being prevented from being supplied into the wind tunnel. Meanwhile, tracer particles having small diameters are deflected by being forced to flow with the deflected air because of their small inertia and are supplied into the wind tunnel without colliding with and attaching to the collision surface 12e. As a result, supply of tracer particles having large diameters into the wind tunnel can be minimized and contamination of the walls and the floor of the wind tunnel by attached tracer particles having large diameters can be prevented.
    • 要解决的问题:提供能够使污染风洞的具有大直径的示踪剂颗粒的比例最小化的播种装置。 解决方案:当示踪粒子与来自播种机13的喷嘴16的空气一起注入罩12中时,空气被罩12的碰撞面12e引导,并且向空气流的下游方向偏转, 风洞,并通过发动机罩12的开口12d流入风洞。由于其大的惯性,具有大直径的示踪剂颗粒不被迫与偏转的空气一起流动。 相反,它们直接移动并与碰撞面12e碰撞并被捕获在那里,从而被防止被供应到风洞中。 同时,具有小直径的示踪剂颗粒由于其惯性小而被偏转空气流动而被偏转,并且被供应到风洞中而不与碰撞面12e碰撞并附着。 结果,可以将具有大直径的示踪剂颗粒供应到风洞中,可以防止通过附着的具有大直径的示踪剂颗粒污染风洞的壁和地板。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a measuring method that measures fluid forces (a drag force and a lift force) applied to an object even when measurement by using a balance is impossible, does not change flowing by insertion of a probe or the like, and does not take a measuring time period as compared to measurement by a pressure probe so as to complete the measurement in a short time, and to provide a measuring device. SOLUTION: This method for measuring distributions of a shape resistance, an inductive resistance and a lift force applied to an object includes the step of measuring a three-component velocity distribution value of rear flow of an object residing in a fluid field, and the step of calculating a pressure distribution by means of a numerical fluid analysis method by using the three-component velocity distribution value as an input. The method further includes a rear flow integration method with the use of the three-component velocity distribution value and the pressure distribution value, thereby calculating out the distributions of the shape resistance, the inductive resistance and the lift force applied to the object.
