Located in the capital city of Abu Dhabi, the Abu Dhabi National Exhibition Center (ADNEC) is a fully equipped, modern venue of more than 73, 000 m2 of live event space that provides a perfect stage for more than 100 events held in the capital every year.
In 2008, DuctSox MENA was selected as the company to install textile ducting to which would provide efficient air supply to the entire area and ensure a pleasant and healthy atmosphere at all times.
CFD SIMULATION
A Computational Fluid Dynamics (CFD) model was constructed for the simulation of the ventilation and cooling of the Abu Dhabi National Exhibition Center (ADNEC). In order to ensure reliable results, a specific scenario was applied and the simulation was performed after the the 3D geometry was reconstructed from existing drawings and CAD files together with the important details.
The scope of the study was to identify whether the air conditioning provided by DuctSox textile ducting satisfied the design basis under worst environment scenario
RESULTS
The figures on the right show the results of the CFD Analysis. The contours of the varying velocity magnitude change colors respectively reaching the highest velocity magnitude of 500 ft/min (Red) and the lowest of 0 (Blue)
. The air is supplied at its highest velocity of approximately 500 ft/min at the regions closest to the duct vents. The velocity then reduces to around 200 ft/min at the airflow and continues to decrease as the air splits and then recirculates around the entire area.
DuctSox air dispersion system ensures a large floor coverage by the air released from the duct As each outlet releases air away from each other at a high velocity magnitude, the individual flows move down towards the floor where the air is “trapped” between the floor and the two incoming streams. This trapped air, along with re circulation zones, propels the two streams near the floor away from each other and distributes the air thoroughly across the entire floor.
CONCLUSION
With the CFD simulation scenario results meeting all of the design criteria required to complete the project, DuctSox MENA was appounted to design of the ducting for the largest exhibition center in the Middle Eastern region – the Abu Dhabi National Exhibition Center. The diameter of the selected ducts was 66’’ while the height of the ceiling 10.45 m. The duct length was 60 meters for each line as well as the CFD modelling.
