A Breath of Fresh Air – Mosen Ltd Developed the Ground Breaking Mojet Tunnel Ventilation System with ANSYS CFD
Mosen Ltd., a leader in engineering consulting services, specializes in tunnel ventilation, fire safety engineering, risk management and tunnel safety.
Using ANSYS computational fluid dynamics (CFD) simulation, Mosen developed the reversable MoJet® tunnel ventilation system, which delivers up to 25 percent more in-tunnel thrust than other jet fans. ANSYS CFD optimized the shape of the nozzles, to direct the airstream away from the tunnel’s soffits and walls. This reduced surface friction, minimizing the Coandặ effect (the tendency of a fluid jet to remain attached to a convex surface) as a result. Simulation also helped reduce the number of fans (significantly lowering maintenance costs), sound pressure levels and system weight.
