Direct Numerical Simulation is applied to simulate two dimensional low Reynolds number flows around NACA0012 aerofoil. The calculation results show negative lift curve slope and the existence of the reverse flow around the trailing edge at low angle of attack. This paper discusses the flow mechanism of negative lift curve slope phenomena from the view point of "Kutta condition violation".
