The article is devoted to issues related to the occurrence of noise and vibration in the centrifugal turbine of ventilation equipment of residential buildings. Airflow in the rotating radial-axial channel representing a simplified configuration of the interblade channel of a centrifugal turbine is studied. Numerical simulation of the airflow in the considered geometrical domain is performed using ANSYS CFX solver. A particular attention is given to different turbulence closures used in the model. Accuracy of the simulation results was estimated with respect to the laboratory measurements by J. Moore [9]. The comparison was carried out for velocity profiles measured at three different cross-sections of the channel under different mass flow rates. |
