METHOD OF USING LASER SHOCK IMPACTS TO PRODUCE RAISED ELEMENTS ON A WALL SURFACE CAPABLE OF BEING SWEPT BY A FLUID IN ORDER TO CONTROL THE INTENSITY OF TURBULENCE IN A TRANSITION ZONE

摘要

A method for producing, on the surface of a wall capable of being swept by a fluid, raised elements forming disruptions of the boundary layer is disclosed. The method includes applying laser shocks to the surface so as to create peaks on the edge of the impact zones such that the peaks form the disruptive raised elements.
