ThermoTun-Online

ThermoTun-Online is a railway tunnel ventilation and aerodynamics software application. It predicts air pressures and velocities caused by trains in tunnels using the industry leading ThermoTun software.

ThermoTun-Online is accessed over the internet enabling you to quickly perform calculations for the following tunnel configurations:

  • Single train in a tunnel
  • Crossing trains in a tunnel
  • Tunnel with an airshaft
  • Emergency ventilation
  • Flared entrance to reduce pressure gradients

ThermoTun-Online allows you to choose from five common train:tunnel configurations.

Train and tunnel parameters are entered in an easy-to-use form, and pressure and velocity results are returned in graphical form and text files which can be imported into spreadsheets.

A demo is available after registration, and extensive help pages offer guidance on the choice of values for input parameters.
