Aerodynamics Performances of Tunnel Jet Fan and its Passage Components Design

Abstract:

Jet fans are widely used in ventilation systems of road tunnels, railway tunnels and subways etc. It was demonstrated that the static pressure generated by jet fan impeller is merely useful for overcoming its own internal flow resistance and can not improve the ventilation state of tunnel. It was pointed out that in the aerodynamic design process, the static pressure of jet fan should be made as small as possible. The effective way to reduce static pressure produced by impeller is the rational design of jet fan passage components.
