Use of CFD Tool Ansys Fluent for Fire Safety Improvement of an Indoor Sports Arena

The focus of the article is the design of a HVAC (heating, ventilation and air-conditioning) system for the main central space of a real multifunctional indoor sports arena. Numerical simulation of the air flow provided a basis to determine the optimal number of fire ventilators, their capacity and placement, and also to determine the maximum air-flow velocity in openings designed for evacuation in the event of an emergency. The ANSYS Fluent 13.0 software one of the world's most sophisticated CFD (computational fluid dynamics) codes was used for the numerical simulation. In this case, the specific problem of a turbulent flow in a complex geometry was under investigation. This study should serve as a base for future installation of the system in the indoor sports arena.
