The performance of modified anchor impellers in stirred tanks is investigated. The classical anchor impeller is taken as a reference, then the upper part of the blade arm is curved at different degrees (α). Three geometrical configurations are explored, namely: α = 0° (which corresponds to the standard shape of anchor impellers), 45°, and 90°. The study is achieved numerically by using a finite volume...
The shape of the tank plays an important role in the hydrodynamic performance of the agitation. A 3D simulation was done using CFD calculation code (CFX16.0). The study was carried out for large Reynolds number: 104–2.105. Navier–Stokes equations governing the phenomenon are solved by a method of discretization finite volume. The turbulence model used is the k–ε standard type. Our main goal was to...
