The King Abdullah Financial District Metro Station in Riyadh, Saudi Arabia, was designed by UK studio Zaha Hadid Architects. The station is one of 85 planned to serve the Riyadh metro. It is one of the largest on the network, serving as an interchange between three lines as well as the under-construction King Abdullah Financial District monorail.

Mechartes assisted the client in designing an effective smoke ventilation system for the metro station through a detailed CFD Smoke Analysis. This analysis evaluated fire scenarios in various areas, including platforms, concourse, mezzanine, and ground levels, utilizing FDS software. Our approach adhered to relevant standards such as NFPA 92, NFPA 130, SFPE, and the Saudi Fire Code.

Upon completing the study, we provided recommendations for the final smoke extract flow rates required for the station, ensuring safety and compliance with industry standards.

Mechartes conducted a CFD flow analysis to examine the airflow inside the axial fans, including the plenum and duct layout installed in the platform area, focusing on velocity and temperature parameters.

Additionally, a CFD analysis was performed for the chiller area to ensure sufficient air intake for the chillers and to identify any potential hot air recirculation from the outlets to the chiller inlets. These analyses ensured optimal performance and efficiency of the HVAC systems, contributing to the overall reliability and effectiveness of the project.
