Experimental study of blade rigidity effects on the global and the local performances of a thick blades axial-flow fan [PDF]

open access: yes, 2010
An experimental investigation on the aerodynamic performances of thick blades axial-flow fans was carried out in this study. Two fans are considered, the first one is rotomoulded (in plastic) and the second one is milled (in aluminium). Both have exactly
