In particular, the air burst has the shape of a toroidal vortex.

The angle of deflection establishes the swirl of air in the cylinder.

For that purpose, the cool air flow or cool air film whirls in the same direction as the combustion air supplied through the burner.

An air swirling insert (26) is disposed within the nozzle body.

He interposes an account of the spherical nature of the Earth, [109a-b] and the finite height of the atmosphere [109c-e]

In air spinning machines the air vortex and the winding of the fibres are extremely important to the quality of the spun yarn (25).

A powdered substance (8) within the chamber is picked up by the swirling air within the chamber and is uniformly and finely divided by the swirling effect of the air.

To this end, the air turbulence level (2) comprises a plurality of turbulence winglets (5) which respectively produce an air vortex (10) extending in the direction of flow.

Air vortex: A spinning funnel of air of varying size, the air vortex can be used to trap or disorient opponents as well as to deflect any objects thrown at it.

The pulse cleaner can be equipped with features such as an exhaust aftertreatment device core temperature sensor, an air flow concentrator or an air swirling vane.

Viewers are invited to leave a bag in the area where there is a vortex of air.

Stronger versions can occur from mesocyclones - which are a vortex of air within a convective storm.

The light proves to be a luminous sphere when it rises without noise while generating a strong swirl of air.

I don't know why, but this circling of blinded air, the steaming waffles, smoking sugar and silver burning like paper, heightened my nervousness unbearably.
