Abstract

A fractal impeller design for stirred tank reactors comprising plurality of main branches, each of which further having plurality of sub-branches with each sub branch having plurality of blades to distribute/dissipate energy in uniform manner and to achieve uniform temperature throughout the reactor while operating it at lower impeller speed to avoid high shear zones; wherein, the angular distances covered by the blades vary and yield variation in the local blade passage velocity for a given impeller rotation speed.
