ZENTRIFUGALGEBLÄSE MIT SCHAUFELN MIT VARIABLER KRÜMMUNG.

摘要

Boundary layer separation in a rearwardly skewed centrifugal impeller can be better controlled by designing the impeller blades with an "S" camber, i.e., with rearward curved radially extending blades in a centrifugal blower. The blades have a positive camber at a radially inward region and a negative camber at a radially outward region of the blade.
