Success Story
Turkish Technic (Turkish Airlines Technic IC) has completed the construction of the new hangars at Istanbul Airport. With an indoor area of 60.000m2, the new complex has the distinction of housing the largest hangars in Turkey and providing services to 3 wide-body and 6 narrow-body aircraft simultaneously. Turkish Technic reached our team here at PROTA to help them compare the effectiveness of three different heating system alternatives using computational fluid dynamics (CFD) analysis.
The primary Project Goal was to analyse and compare three different MRO hangar heating system alternatives and select the best solution in terms of cost and performance. The 16500 m2 enclosed hangar area is to be heated for the comfort of the engineers, technicians and operators. Three heating alternatives were studied using Autodesk CFD: 1) Underfloor heating 2) Overhead radiant heating 3) Hybrid heating (underfloor and overhead radiant heating)
On a cold winter day, when hangar doors are opened to take an airplane in or out of the hangar, hangar volume quickly cools down by the cold air rushing in from outside. After the hangar doors are closed, it takes some time for the hangar volume to heat up. The MRO hangar was modelled with 6 narrow-body airplanes in it. The cooling and heating phases was studied using transient natural convection analysis. Radiation heat transfer was also taken into account.
The optimal heating alternative, superior in terms of cost and performance, was identified and selected without expensive and time consuming field testing.
PROTA modeled and analyzed three different heating systems for the Turkish Technic MRO hangar using Autodesk CFD. Transient natural convection air flow in the hangar was simulated taking radiation heat transfer into account. Airflow patterns and temperature distribution were visualized, and a heating system superior in terms of cost and performance was identified and selected based on CFD simulation rather than estimation.
