Author(s) : BOMMES L., KLAES K.

Type of article: Article


The article investigates certain conditions in which the energy transferred to the air is converted into sound in a centrifugal fan. These conditions are the flow pattern at the intake of the fan (which can be modified by a curved pipe introducing a turbulence) and the shape of the fan impeller blades.
