Abstract

Particle Image Velocimetry(PIV)technology is used to study the impact and measure the turbulent boundary layer of V-shaped, trapezoidal groove and smooth plate under zero pressure gradient.Comparable measurement is conducted to inspect the average velocity and wall shear stress at the same location under the same flow rate.The local drag coefficient of grooves and smooth plate is calculated by using the loss of momentum and Lugwieg & Tillman experience formula method.The results show that groove can'increase the thickness of viscous sublayer and decrease wall shear with obvious drag reduction effect.
