Investigation of Forced-Air Duct Leakage Phenomenon Using CFD Methods for Underground Tunnel Construction

Autor: Maciej KOSOWSKI, Pavel ZAPLETAL, Grzegorz PACH

Publikováno v: GeoScience Engineering, Vol 68, Iss 1, Pp 58-69 (2022)

Using CFD, the paper deals with a simulation of all phenomena related to forced-air duct fitted with a fan, with the emphasis on unit aerodynamic resistance and untight air ducts. We created a 3-dimentional model of the system including perforations

UPDATING THE AERODYNAMIC RESISTANCE FOR SUBSURFACE VENTILATION

Autor: PAVEL ZAPLETAL, MACIEJ KOSOWSKI, MICHAL VOKURKA

Publikováno v: GeoScience Engineering, Vol 65, Iss 1, Pp 37-45 (2019)

For the safety works in the mines, good ventilation is one of the main requirements. For miners’ performance, the subsurface ventilation creates healthier and more hygienic conditions. The mine ventilation has always belonged to the field of mining
