ThermoTun - Examples

This pagie illustrates some - but by no means all - of the features available in ThermoTun. The chosen examples are indicative of practical applications, but they are not representative of particular tunnels.

In each case, some features of the example are highlighted in a brief introduction and graphical output is provided to illustrate the outcome.

Example 1 The use of tunnel modifications to reduce pressure fluctuations experienced by passengers on a high speed train
Example 2 Velocities induced in at the ends of tunnels in a rapid transit system
Example 3 Use of shaft fans in an undersea tunnel
Example 4 Use of jet fans to maintain minimum air flows past a stationary train
Example 5 Development of pressures during nose-entry to a tunnel with a portal hood
