ABSTRACT:
A concentric multiple tube assembly forms an axial eductor passage for educed ambient air flow unobstructed from the inlet end to the outlet end. Ambient air eduction occurs as a result of ejection of compressed air or compressed air and water via at least one set of compressed air and water ejection orifices oblique to the inner tube sidewall defining the eductor passage and at a skewed trajectory angle such that the compressed air streams attach to the inner tube side wall opposite the orifices ejecting the same via Coanda effect. By wall attachment, a water film on the tube inner wall enhances the cooling effect of the air stream passing therethrough by evaporation thereof. Compressed air and water are delivered to annular chambers within the tubular assembly. Preferably, water mixes with the compressed air in one of the chambers prior to ejection into the eductor passage. A circumferential set of outlet end air and water ejection nozzles eject compressed air and water in jet form at circumferentially spaced positions parallel to and about the air/water stream discharging from the outlet end of the assembly.
