Montgomery Tunnel Ventilation

A series of experimental measurements and 3D CFD calculations were undertaken to compare the air velocities, effective thrust and power consumption of two types of ventilation systems at the Montgomery Tunnel in Brussels: conventional jetfans and MoJets. The MoJet solution was shown by the CFD analysis to provide approximately 100% more thrust compared to conventional jetfans, with lower power consumption per fan. These results were confirmed by the experimental measurements undertaken in an empty tunnel. The MoJet therefore offers a cost-effective and environmentally friendly option for new and existing longitudinal tunnel ventilation systems.
