Abstract
The present invention embraces fluid flow apparatus comprising a first nozzle for discharge of a first fluid therefrom, duct means for receiving the first fluid discharged from the first nozzle and for discharging the first fluid therefrom, and a second nozzle for discharge of a second fluid therefrom for modifying the first fluid upon discharge from the duct means. The present invention also embraces a method of controlling the environment of the fiber forming region of a glass fiber forming bushing comprising establishing a first flow of fluid in which the fluid in the center region of the first flow has a flow velocity at least as high as the flow velocity of fluid in all other regions of the first flow, directing a second flow of fluid into contact with the first flow to establish a combined flow in which the fluid in the center region of the combined flow has a flow velocity lower than the flow velocity of fluid in other regions of the combined flow and contacting the fiber forming region with the combined flow.
