The manufacture and development of materials very often involves agitation or mixing. The mixing system of the vessel is always an important aspect of design, because the involved processes (chemical reaction, heat or component transport) need adequate mixing, and phase homogeneity. In our work we propose a mobile of agitation which does not exist in the literature it is the case of a chamfered paddle impeller. The hydrodynamic and mass characteristics of this impeller have been investigated in the case of viscous Newtonian fluids. 2D finite volume based computational fluid dynamics (CFD) simulations have been carried out. It was found that the chamfered paddle impeller could reduce mixing time compared to that obtained by the straight impeller in laminar flow region. The effect of the degree of chamfering impeller on mixing time was also studied and a significant reduction of mixing time was observed.
