    Kształt pola prędkości w wyrobiskach przewietrzanych wentylatorami wolnostrumieniowymi - symulacja numeryczna przy użyciu lepkościowych modeli turbulencji
    (Wydawnictwa AGH, 2010) Branny, Marian; Filek, Krzysztof; Nowak, Bernard
    Room and pillar headings are frequently ventilated with the use of jet fans. The range of penetration of an air stream generated by the jet fan is determined by several parameters; the major determinants being the initial stream parameters and the place of fan's installation. The paper presents a method of calculation 3D velocity fields in room and pillar headings. Results obtained with the use of three turbulence models, it is two equations model k-l i k-u SST and one equation of Spalart-Allmaras. Calculation were compared with measurements [Meyer 1993].
