Abstrakt: The paper pertains to the assessment of indoor air quality in terms of its air age in a ventilated space. It involves a comparison of Computational Fluid Dynamics (hereinafter CFD) simulation software and their validation by an experiment carried out in a test chamber. A total of 14 cases were simulated and compared using the software: OpenFOAM, Blue CFD-AIR, DesignBuilder, and Ansys. The aim is to evaluate the accuracy and usability of the software by comparing selected computational domains and meshes. The results obtained show that the assessed software achieves satisfactory accuracy for air velocities and air ages. Models with simplified inlet geometry and half-domain offer the best balance between accuracy and computational effort.
Klíčová slova: air age; Ansys Fluent; DesignBuilder; OpenFOAM; validation
