An exhaust duct through which an exhaust gas jet from a gas turbine engine flows comprises a duct wall, an inlet, an outlet and an eductor. The inlet, through which the exhaust gas jet enters the exhaust duct, is positioned at an upstream end of the exhaust duct. The outlet, through which the exhaust gas jet exits the exhaust duct, is positioned at a downstream end of the exhaust duct. The eductor is positioned proximate the downstream end. In one embodiment, the eductor comprises a perforated wall segment of the duct wall through which ambient air from outside of the duct wall is permitted to enter the exhaust duct. In yet another embodiment, the eductor is diverging.
