Agitated reactors/tanks are widely used in many industrial processes. The performances of macromixing and micromixing are of importance to the optimal design of stirred reactor, especially when involved fast complex reactions. In this paper, macromixing and micromixing were studied by experimental approach and using numerical simulations.The mixing time experiments were carried out in a perspex vessel of 0.476m in diameter. The mixing time was measured by using a conductivity probe. Single and multiple stan...
