dc.description.abstractIn this thesis, the object was to investigate flow-induced noise in the fire labyrinths of the elevator landing door. The aim was to locate the noisy structures by means of experiments and to produce a development proposal. In addition, the target was to experimentally investigate the leakage flow rate of the landing door and to examine the suitability of various turbulence models for estimating the leakage flow rate by CFD simulation. The landing door was processed in the laboratory as small sections constructed from different parts of the fire labyrinths. The 1/3-octave band measurements were performed in the door laboratory of KONE Corporation in Hyvinkää. Estimates of flow rate and the sound power radiating from the whole door was derived based on the measurements. The door under consideration creates noise that is accompanied by pure tones. By modifying the structure of the fire labyrinth, a pure tone was eliminated and the sound power level of the door decreased by 5 dB. CFD simulation proved to be a useful tool for estimating leakage flow rate through the fire labyrinths.en
