Mosen Ltd has patented the unique MoJet® tunnel ventilation system, which has been adopted in a number of metro and road tunnels worldwide. This patented device can enhance the aerodynamic thrust delivered by jetfans by 20% to 60%. It does this by using convergent nozzles to accelerate the flow and turn it away from the tunnel soffit and walls, thus reducing friction between the jet and the tunnel surfaces. The reduction in aerodynamic friction leads to significantly improved energy efficiency, as well as fewer jetfans being required to provide tunnel ventilation.
