Tunnel Ventilation & CFD.
Tomaers is a recognised specialist in tunnel ventilation engineering — combining aerodynamic analysis, 1D/3D CFD simulation, and jet fan optimisation to deliver safe and efficient ventilation strategies for road, rail, and utility tunnels. Our engineers apply PIARC methodologies and international best practice to model complex fire and congested traffic scenarios, ensuring tenable conditions for evacuation and firefighter intervention. We have contributed to ventilation design on some of the most demanding tunnel projects across India, the Middle East, and Europe.
