Micro riblets have been designed and fabricated by surface-micromachining technology with 3-layer polysilicon and 2-layer phosphosilicate glass (PSG). The riblets with rib-peak-widths of 3, 4, 6 microns and spacing of 100 microns and 300 microns have been chosen. Several more complicated surface patterns like fish scale replica, have also been designed. On the same chip, the micromachined hot film shear stress sensor with different geometries (6 x 100, 12 x 100, 18 x 100 microns x microns, etc.) are integrated downstream from the micro riblets. The sensors are made of polysilicon and used for the shear stress measurement of the fluid flowing over micro riblets.
