Hello Fahmi,
In the laminar static mixer model, the geometry of each blade is obtained by an extrusion with a 30 degree twist angle. See the mph file for the exact details.
More complex blade geometries can be created in other ways such as by lofting using the Design Module, see www.comsol.com/design-module and in particular this image cdn.comsol.com/products/design/impeller_collage_1024x835.png
