AbstractA pair of small but finite-amplitude oblique waves were used as initial condition in numerical simulations of transition to turbulent flow. A rapid energy growth to a transition peak occurred. Although this transition scenario is triggered by a nonlinear interaction, the dominant mechanism yielding substantial disturbance amplitudes was found to be linear. A number of simulations were made that showed that the overall features of this transition scenario remains the same for a range of parameter values.
