Select Tunnel

ThermoTun Online allows users to choose from 5 standard tunnel configurations (cases):

1. Single train in a tunnel
2. Crossing trains in a tunnel
3. Tunnel with an airshaft
4. Emergency ventilation
5. Flared entrance to reduce pressure gradients

You can run each case as a demo or for professional purposes. In the demo mode (which is free), you choose from a small number of pre-determined options. In the professional mode, you specify parameter values applicable to your own tunnel application.
