Tunnel ventilation and Industrial ventilation
In recent years contemporaneous with the advancement of technology, special consideration needs to transport infrastructure have been raised. One of the main methods of transportation is road and rail transportation. The main feature of these methods is their generality, which requires special attention to the design details.
One of the most important aspects of road tunnels is ventilation. Tunnel ventilation has a direct impact on car passengers' health. So tunnel ventilation could be designed using Jet-fans or other ventilation methods. We have good experience in tunnel ventilation design, using jet-fan(longitudinal tunnel ventilation method). We can handle tunnel ventilation design projects in the middle east(Iraq, Kuwait, Oman, UAE, and KSA)
We can also handle tunnel ventilation simulation(CFD) and fire and smoke simulation in tunnels(PyroSim, FDS)

Design and Simulation of road and rail tunnel ventilation
The new drilling techniques and TBM devices have led to the possibility of digging long tunnels in less time than usual. One of the requirements for digging long tunnels is proper ventilation. The most common method of urban tunnels ventilation is the longitudinal ventilation using jet fans.
To cause proper and healthy ventilation in tunnels, additional to equipment, correctly design and detailed calculations of pollutants and environmental conditions are needed.
To carry out tunnel ventilation computing feasibility studies, some processes must be performed regularly and with a particular order. To basic acquaintance with tunnel ventilation calculation process, the main steps of the process, will be mentioned as followed:
Finding out technical drawings and geographical position of the tunnel
Studying the Climatic traffic characteristics of the region and view
Studying the status of pollutants produced by vehicles and analysis of traffic statistics
Calculations to determine the required flow rate for ventilation in traffic and fire mode
Studying different methods of ventilation and selection of the appropriate method
Flow simulation inside tunnels with Fluent, SES and flow works software
Figuring out all ventilation equipment on the chosen method, along with Technical Specification
Araco by having the suitable knowledge, work experience in the field of tunnel ventilation and utilizing Finite element flow simulation techniques is present to carry out projects in road and rail tunnel ventilation design with high certitude and quality.
Design and simulation of industrial ventilation and local ventilation - CFD
Improved ventilation and sanitary conditions inside the silo and factories in addition to raising the efficiency of labors play a fundamental role in reducing the damage caused by pollutants, the equipment inside the workshop and the factory. In fact, the purpose of the design of industrial ventilation is not necessarily heating and cooling, but also reducing the concentration of pollutants in the environment by removing emissions and getting fresh air.
Environmental pollutants can include different items:
1- Pollutants produced by internal combustion engines such as diesel generators, forklifts and heavy machinery, which are mainly in the form of combinations of carbon and nitrogen and soot in the environment.
2- Chemical contaminants that are generally caused by chemical processes within the production line in many industries, including the production of zinc, steel, acid production, mushroom production, and even Aviculture. This type of pollutants in addition to severe injuries to personnel health, cause severe corrosion of equipment.
3- Particulate, this type of contamination is extremely common in the manufacture of cement, steel, fiberglass and rock wool, Woodworking Shops and Coal production workshops. This particulates in the absence of proper ventilation after breathing, causing acute and chronic diseases and at the same time can severely damage the electrical circuits and mechanical equipment.
According to late subjects, it is recommended that for the design of industrial ventilation for warehouses, factories and workshops with using a Jet fan or axial fans reviews of the professionals must be used, not just dealers. However, after simulations of airflow inside the enclosure, the resulting data to be matched with the nearest weather station information.
Design and Simulation of parking ventilation using jet fans
Construction and operation of commercial and office complexes are highly booming, according to the optimal use of existing spaces in major cities.
Due to the compression of space in such complexes, parking is designed with the assumption to use the most space possible. Large numbers of cars in parking and enclosed spaces, it will be certainly necessary to design a very powerful ventilation system. In such situations, we recommend using jet fans for parking ventilation. At the same time, for the installation of such a ventilation system, it must first be carried out to simulate the flow rate in the parking.
It should be noted that due to the high cost of this type of ventilation system, design and simulation must be carried out by the consulting companies. Designing by manufacturers and retailers can lead to a sharp increase in project costs.
PyroSim and FDS simulation and project
PyroSim is a graphical user interface for the Fire Dynamics Simulator (FDS). PyroSim helps companies to create and manage the details of complex fire models.
PyroSim and FDS are both using as main software to simulate the fire reaction in different environments like Building, parking lot, Subway, Tunnel, Cinema, Commercial office complex and…
Meanwhile, it is possible to define smoke detectors and sprinklers in the 3D model, to examine the current design in case of fire with both software.
Meanwhile, it is possible to link PyroSim results with Pathfinder software which is advanced movement simulation combined with high-quality 3-D animated results, gives reliable answers.
