Abstract
The effect of the disturbance on the laminar-turbulent transition of the mixing layer is experimentally investigated. So far, two kinds of experiments were conducted with the Reynolds number of 5000; in one, the plates at the nozzle exit do not protrude into the nozzle section and remain in a 'stationary state' and in the other, 'anti-symmetrical oscillating state', the plates oscillate perpendicularly to the flow and anti-symmetrically with each other in relation to the flow. In the present study, the Reynolds number was decreased to 3000. The effect of the Reynolds number was examined.
