壁面せん断応力センサ MicroPro™

The microPro™ shear stress sensor measures the wall shear using a near-wall traversing 1-D miniLDV. It is designed to automatically obtain the mean velocities at a number of points within the log region and possibly within the linear region of laminar or turbulent boundary layer. The velocity data are then used to obtain the best estimate for velocity gradient at the wall. Knowing the coefficient of viscosity, the wall shear stress is then calculated. MSE’s microPro shear stress sensor requires no alignment or calibration by the user.
