Meiginger's equation for a jet fan cannot be applied to the case in which jet fans operate against air flow to reduce its velocity in a tunnel. This operating mode is used during fire accident in the tunnel. The equation for the mode is shown in this paper and is examined through the model experiments. The efficiency and diffusion of jets equipped with a deflector flap for the normal tunnel ventilation mode are also examined through the model experiments including flow visualization. Application of the flap is recommended.
