N2 - To reduce aerodynamic noise generated by a pantograph panhead, a flow control method is applied to the panhead. First, a plasma actuator is applied to the panhead surface to verify that flow control can control flow separation and reduce turbulence intensity behind the panhead. Second, based on the flow control mechanism derived from the experiments applying the plasma actuator, a more practical flow control method is proposed using air suction as an alternative. Experimental results show that air suction near the separation point can reduce narrow band aerodynamic noise from the panhead.
