Create a VentFIRE script and simulate each person or group of people as an oxygen consuming material. You can define this in the combustibles presets and define how much oxygen is consumed and the CO2 produced for each person. Then specify the metabolic rate to produce 100-150 Watts per person. The simulation should predict the decrease of oxygen and increase of CO2 over time. Diesel simulation in VentSim does not consider oxygen. But VentFIRE diesel burning does. The fire script can remain the same - if you simulate it over a long time it will become stable and steady state. Mines do not consider people oxygen consumption because the ventilation systems are designed for diesel machines which far exceed human requirements.

How can we simulate the oxygen consumption of a large group of people standing in a designated area?

We now offer Ventsim™ Lite licences for students to download and install on their own computers (at no cost). While this version is very restricted on features (only airflow simulation on up to 500 airways), it will complement the much more powerful commercial version and give students a great introduction to the software. Please refer to www.ventsim.com/products/ventsim-lite/ for more information.

Do you have any deals for students who are learning to use Ventsim™?
