Abstract
Measurements of wall shear stress streaks of a turbulent boundary layer in the channel flow were carried out using MEMS-based micro shear stress imaging chip, which contains 85 sensors. The chip is designed and fabricated by surface micromachining technology. One array of 25 micro shear stress sensors in the chip that covers a length of 7.5 mm is used to measure the instantaneous spanwise distribution of the surface shear stress. The statistics of high shear stress streaks were established. Based on the measurement, the physical quantities associated with the high shear-stress streaks, such as their length, width and peak shear-stress level, were obtained.
