VENTO AEC 2022 has arrived!

We are pleased to announce that we are releasing the new version of VENTO AEC.

Plenty of new features, for both pre- and post-processing, and a revamped Graphical User Interface.

What we show in this post is an “incidental” simulation, a car fire in the center of Milan. First, the standard stationary wind analysis is carried out, then a transient simulation of the incident follows.

We assigned time-varying heat and soot release (see the attached images) and carried out 40 time steps of 15 seconds each (10 minutes). The fire is extinguished in about 7, 8 minutes.

The wind is coming from East at 3 m/s (using a log atmospheric wind profile). The car fire position (shown in one of the attached images) is well sheltered from the wind and the heat and soot plumes initially rise almost vertically till the height of “Grattacielo Pirelli”, which can be easily recognized in the background. The soot is then transported by the wind and will eventually be brought to the ground level many hundreds of meters forward.

Below 3 images show the wind velocity maps at 1.5, 30 and 100 meters above the ground.

Last but not least: the overall pre-processing time was some 10 minutes, including the grid generation. Yes, so little time! Thanks to our non-conformal-grid technology.

Video of the transient analysis can be done easily by VENTO AEC.
