RT Journal Article SR Electronic A1 Zavila, Ondřej A1 Mička, Vladimír A1 Bernatíková, Šárka A1 Kaličáková, Zdeňka T1 Logical Succession in Ventilation Systems of Industry Hall in Connection with the Issue of Spreading of Heavy Metal Microparticles JF Acta Mechanica Slovaca YR 2016 VO 20 IS 3 SP 12 OP 18 DO 10.21496/ams.2016.019 UL https://www.actamechanica.sk/artkey/ams-201603-0003.php AB This article deals with problems of ventilation system and distribution of heavy metal microparticles in the interior of an actual industry hall. The case study being presented demonstrates not only the most significant and often logical mistakes of ventilation systems in industry halls, but also an example of possible systematic way of finding technical solutions. CFD code ANSYS Fluent was used for creation of three-dimensional numerical mathematical simulation of the problem. This case study could be used as an inspirational example of how similar problems in industry halls could be identified and solved systematically.
