An airflow proximate to leading edges of a turbofan nacelle is ejected substantially normal to a fan face of the turbofan, creating suction proximate to the leading edge and mitigating flow separation proximate to the leading edge. One embodiment comprises a turbofan engine that includes a nacelle, a bypass fan, and a recirculation channel. The recirculation channel is disposed within the nacelle and has a recirculation channel inlet downstream of a leading edge of the bypass fan. The recirculation channel has one or more recirculation channel outlets upstream of the bypass fan that are proximate to a leading edge of a nacelle inlet, where the recirculation channel outlets redirect an airflow from the recirculation channel towards an inside edge of the nacelle inlet to mitigate flow separation at the leading edge of the nacelle inlet.
