Development of point source disturbance in the three-dimensional boundary layer of yawed circular cylinders is studied using Direct Numerical Simulation (DNS). Using a 2D FFT technique, the waves are separated into two instability modes. One is the streamline-curvature instability and the other is the cross-flow instability as predicted theoretically. It is shown that the T-S wave type instability appears when the frequency of excited disturbance is high, while the cross-flow instability becomes dominant when the frequency is low.
