The performance of a rotating stirrer made of helically positioned paddles is experimentally analyzed. The statistically independent positions are computed as a function of the number of paddles, paddle separation and relative tilt angle. With respect to a traditional single paddle wheel stirrer, the structure combines a helical path and just a simple engine required for the rotation. The analysis reveals an improvement in the lower frequency range where the chamber performance is more critical. The number of the paddles is limited by the distance and the tilt angle.

Abstract
The performance of a rotating stirrer made of helically positioned paddles is experimentally analyzed. The statistically independent positions are computed as a function of the number of paddles, paddle separation and relative tilt angle. With respect to a traditional single paddle wheel stirrer, the structure combines a helical path and just a simple engine required for the rotation. The analysis reveals an improvement in the lower frequency range where the chamber performance is more critical. The number of the paddles is limited by the distance and the tilt angle. The correlation between two adjacent paddles is also analyzed as function of the distance and the tilt angle. The activity suggests the need for optimization of all parameters.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
