Simulation of Entropy Generation under Stall Conditions in a Centrifugal Fan
Entropy, 2014 Rotating stalls are generally the first instability met in turbomachinery, before surges. This 3D phenomenon is characterized by one or more stalled flow cells which rotate at a fraction of the impeller speed. The goal of the present work is to shed some
