Abstract
1 VSB Technical University of Ostrava, Faculty of Safety Engineering, Department of Fire Protection, Ostrava, Czech Republic, ondrej.zavila@vsb.cz Abstract: 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 fl ow provided a basis to determine the optimal number of fi re ventilators, their capacity and placement, and also to determine the maximum air-fl ow 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 fl uid dynamics) codes was used for the numerical simulation. In this case, the specifi c problem of a turbulent fl ow 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.
