Investigation of the effects of initial disturbances on plane channel transition Conference Paper

abstract

• Transition in plane channel flow is studied using the numerical solution of the three dimensional, time-dependent Navier-Stokes equations. Threshold amplitudes for the various modes of ribbon-induced transition have been determined for Re equals 500 while random noise was used as the background disturbance. The results for ribbon-induced transition are consistent with the analytical work of Herbert and the experiments of Nishioka. Surfaces of constant streamwise vorticity resemble experimental smoke visualizations. Vortex lines computed from the data indicate the development of hairpin vortices.
