<P>PROBLEM TO BE SOLVED: To provide a method of forming a fluid line with an inner contour that has wave peaks and wave troughs. <P>SOLUTION: In a fluid line comprising an inner contour 2 structured with wave peaks 4 and wave troughs 5, for optimizing a flow with respect to a predetermined flow through direction, symbolized by arrow 3, and a method of forming the fluid line 1, each wave peak 4 has a front flank 6 and a rear flank 7, and the front flanks 6 are structured with an inclination angle, relative to a longitudinal axis, shallower than an inclination angle of the rear flanks 7. <P>COPYRIGHT: (C)2013,JPO&INPIT |
