Cofimco extensive research and the application of aerodynamic concepts to fan blades trough computational fluid dynamic analysis (i.e. CFD simulation) and laboratory tests pointed out in the development of a new innovative patented design: the Tandem Blade. Scope of the present study is to examine the aerodynamic basis which determinates the fan blade efficiency, and then shows how the new design can lead to an increase in the fan performances by increasing lift and reducing vortexes generated by the blade.
