A nacelle assembly for a turbine engine has a cowl. The cowl extends along an axis and has an exterior surface spaced from an interior surface. The interior surface forms an air inlet for directing airflow to the turbine engine. An opening is disposed on the cowl. A device for creating suction through the opening is in fluid communication with the opening. The opening removes a portion of a boundary layer flow through the cowl, thereby providing higher energy flow along the interior surface.
