A Polish research institute has developed a set of simulators of air & gas contaminants flow in tunnel or pipeline networks, based on a one-dimensional flow concept with various degrees of complication, & customised to the range of phenomena considered. Both steady state and transients are modelled including impact of a source of fire, inflow of contaminants or natural ventilation, heat exchange, buoyancy, auto-compression. They are looking for commercial agreement and technical assistance.

Operation of complex ventilation networks can be managed with the help of simulators. This kind of software enables forecasting and optimisation of costs and prevention of hazards. Simulation of flow in ventilation networks of underground structures or pipelines is usually based on one-dimensional approximations, due to the extent and complexity of the geometry of the subject. Depending on the range of the phenomena being considered, various levels of simplification are necessary. The development of a network model requires preparation of accurate data from measurements or components' technical specifications. Proper implementation and maintenance of a simulator includes both data acquisition and interpretation of calculation results. Benefits of use can be magnified if the system is capable ok:
- Linking presentation of results with a scheme of the network
- Extracting data for further analysis and prepare printed reports
- Forecasting propagation of contaminants
- Simulating impact of a fire on distribution of flow
- Co-operating with monitoring systems
The development of the system resulted from extended study and experiments. The Polish institute has introduced a set of simulators in various underground mines, maintaining and extending their capabilities. The system was also used for academic education and training of both ventilation engineers and rescue team managers.

Innovative Aspects:
- Simulation of real-time processes of propagation of contaminants and fire gases with animation displayed on the scheme of network
- Co-operation with monitoring systems in order to trace possible location of fire or a source of contaminant.
- Prediction of zones endangered with the propagation of noxious gases

Main Advantages:
- Easy-to-use graphical interface with various modes of graphical presentation of results.
- Wide range of applications from routine management to simulation of hazards like fire or inflow of explosive or toxic gases for development of counter-action strategies and training of rescuers
