Abstract: This paper presents hot-wire measurements in a wind tunnel, close downstream of basic models of blade sections being representative for low-speed, low-Reynolds number axial fans, in order to explore the signatures of vortex ...

Abstract: The paper presents a comprehensive analytical model for the characterization of von Karman vortex shedding in the wake of models of low-speed axial fan blades. The elaborated minimal model is based on the Reynolds-averaged ...

Abstract: Abstract. The subject of the paper is the phenomenon of shedding of vortices (termed herein as profile vortex shedding) from the region being upstream of the trailing edge (TE) of sections of blade profiles. The shed ...
