Grooved Channel Self-Sustained Oscillation Wall Shear Stress Electrochemical Method

The development process of self-sustained oscillation in a grooved channel, in the stream-wise direction, is studied by the electrochemical method. The unsteady wall shear stress measurements show that the flow periodicity in the stream-wise direction is preserved after the onset of the self-sustained oscillation. However, as the Reynolds number is further increased, the flow periodicity is not kept and the magnitude of unsteadiness increases in the downstream direction.
