Abstract
Tracer particles together with air are jetted from a nozzle of a seeder into a hood, the air is guided by a collision surface of the hood, deflected to a downstream side in an airflow direction in a wind tunnel, and flows out into the wind tunnel through an opening of the hood. Tracer particles having a large diameter fly straightly without being drifted by the deflected air and collide with the collision surface and are trapped thereon and are prevented from being supplied into the wind tunnel. Tracer particles having a small diameter are drifted by the deflected air, thereby deflected, and supplied into the wind tunnel without collision with and adhesion to the collision surface.
Claims19
A seeding device for supplying a wind tunnel with tracer particles jetted together with air from a nozzle of a seeder, the seeding device comprising:
- a collision surface inclined with respect to a jetting direction of the tracer particles from the nozzle;
- and
- a hood which covers the nozzle and the collision surface on an upstream side in an airflow direction in the wind tunnel, and which has an opening formed therein on a downstream side in the airflow direction, wherein
- among the tracer particles jetted from the nozzle,
- tracer particles having a large diameter collide with the collision surface and are trapped thereon, and
- tracer particles having a small diameter are supplied into the wind tunnel through the opening of the hood,
- wherein a flange is formed to extend over a substantially entire portion of the opening of the hood where the tracer particles supplied into the wind tunnel pass, the flange being folded inwardly at an obtuse angle.
A seeding device comprising a hood for guiding air and tracer particles jetted from a nozzle of a seeder to deflect a flow passage, the seeding device configured such that the deflected air and tracer particles are supplied into a wind tunnel through an opening of the hood, wherein
- a flange is formed to extend over a substantially entire portion of the opening of the hood where the deflected air and the tracer particles supplied into the wind tunnel pass, the flange being folded inwardly at an obtuse angle.
