Analysis of the velocity distribution in different types of ventilation system ducts
UTP University of Science and Technology in Bydgoszcz, Faculty of Mechanical Engineering, Control Group, Poland
Published online: 4 June 2018
The paper presents the results obtained during the preliminary studies of circular and rectangular ducts before testing the properties elements (elbows, tees, etc.)of rectangular with rounded corners ducts. The fundamental problem of the studies was to determine the flow rate in the ventilation duct. Due to the size of the channel it was decided to determine the flow rate based on the integration of flow velocity over the considered cross-section. This method requires knowledge of the velocity distribution in the cross section. Approximation of the measured actual profile by the classic and modified Prandtl power-law velocity profile was analysed.
