Device and method for producing an impingement air jet in the form of an annular swirl and turbocharger with such a device

The apparatus has fluidic control elements (1,1') comprising an input branch (2) that has an input opening (21) through which cooling gas (G) is fed, and two output branches (31,32) which are formed downstream of input branch. The outlet openings (8) are formed in two output branches. A control...

Zusammenfassung:	The apparatus has fluidic control elements (1,1') comprising an input branch (2) that has an input opening (21) through which cooling gas (G) is fed, and two output branches (31,32) which are formed downstream of input branch. The outlet openings (8) are formed in two output branches. A control element (S) is provided for controlling flow of gas from input branch into one of output branches alternatively. The gas is discharged at outlet openings with average discharge velocity and frequency (f) to produce annular fluid impingement jet (7). Independent claims are included for the following: (1) turbomachine; and (2) method for producing vortex ring forming impact beam.
