ThermoTun-Online is a railway tunnel ventilation and aerodynamics software application. It predicts air pressures and velocities caused by trains passing through 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:
8th April 2016:
New Case 6 - Micro Pressure Waves
A new case case been added to ThermoTun Online. It predicts micro-pressure waves outside a tunnel portal when a strong wavefront in the tunnel reflects at the portal.
ThermoTun Software Update
ThermoTun is continually updated. The latest version represents skin friction in a more general manner that was previously possible. This could cause small differences between current predictions and previous predictions using identical data. The differences are too small to have design implications, but the new predictions are believed to be slightly more accurate.
Returns results in graphical and tabular format.
ThermoTun-Online allows you to choose from six 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.
