Fan for ecological condition sustain in tunnels.

Author(s) : BENISEK M., ILIC D., CANTRAK D., et al.

Summary

The reversible jet fan for ecological conditions in tunnels is an axial fan, with specific impeller construction, which can work in both directions, with almost identical characteristics, depending on the pressure difference at the tunnel inlet and outlet. Jet fans are distributed in a cascade row on the tunnel ceiling. Whole impeller specific energy is transformed into the kinetic part producing big jets and high forces for accumulated moving or standing motor vehicles gases evacuation. Jet fan has been developed in cooperation with the Hydraulic Machinery and Energy Systems Department Faculty of Mechanical Engineering University of Belgrade and company Rudnap Group Minel Kotlogradnja from Belgrade. The fan was tested on the Department Laboratory test rig. Impeller diameter of the fan model is D(em) = 500 mm. Characteristics of the other fans impeller diameter sizes could be scaled-up on the basis of the similarity law.
