Natural and forced ventilation in a mine

Have you ever wondered how air circulates in complex indoor environments like #mine #tunnels? ⛏

Our collaboration with @Italmineraria SrL focused on analyzing and optimizing indoor #aircomfort within a 14-kilometer network of #mountaintunnels.

Using VENTO's "Air Exchange" feature during post-processing, we identified where air is quickly refreshed and where old air tends to stagnate.

The video showcases a 3-hour transient simulation across 180 frames at 1-minute intervals. The four clouds represent varying concentrations of new air mixing with the initial old air: from the red cloud (mostly old air) to the blue cloud (mostly new air), with yellow and light blue clouds in between.

External wind conditions affect pressure variations on the mountain side, influencing natural ventilation efficiency.

Poor air circulation in the lower tunnels was improved by placing a fan at the mine’s lowest point, significantly enhancing air quality and comfort throughout the tunnels.
