Summary:A ventilation device that enhances the effective longitudinal thrust of a fan assembly installed within a tunnel or other internal space. The nozzle trailing edge (6) is tilted so that it forms an angle (13) with respect to the fan centreline (7), with the surface of the nozzle throughbore being non-cylindrical in shape. The discharged flow (5) is turned away from the surrounding surfaces by a convergent-divergent bellmouth (1).
