Numerical Simulations are made by integration of the three‐dimensional Navier‐Stokes equations for the early stages of the turbulent spot development in accelerated flat plate boundary layers. Serveral initial finite amplitude disturbances are stretched and develop a steep velocity gradient in the spanwise direction. The structure, visualized by tracer particles, becomes more complex and looks similar to a turbulent spot, shown in experiments by Elder.
