Forward curved squirrel cage fans enjoy wide application in ventilation systems and power plants due to their simple construction and low noise. Developments in Turbomachinery Flow explores the forward curved squirrel cage fan as an excellent instrument for fluid mechanics research in turbomachines. Phenomena such as jet/wake interaction, circulation, separation and noise in turbomachines are also presented. This book addresses these characteristics which are specific to this fan and applications in other centrifugal turbomachines. The first chapter starts with a general introduction that includes research techniques and a survey of older research. The next chapters focus on two points of view: the first is a detailed description of improvements for different parts of the fan, including the inlet, the rotor and the volute. The second is a comprehensive discussion on geometrical modifications that could improve performance without impacting cost. These issues cover both theoretical and practical aspects of turbomachines flow/design which are helpful for researchers and designers.

explores how forward curved centrifugal fans have wide industrial application discusses the strong trade-off between fan aerodynamics and construction cost provides a wide selection of optimums for geometrical configuration introduces new geometries that can improve performance and reduce noise for the same construction cost presents fluid phenomena as a potential research field for this fan.
