Abstract:

 A mechanical agitation system is primarily intended to provide mechanical energy to the fluid and
therefore promote intimate contact between the substances or phases for obtaining the best conditions in the mass and
heat transfer. When addressing a problem of a stirring-mixing, the first question we should ask is the type of mobile used
to achieve the objectives of the mixing process. This work proposes mixing equipment that studies the mass transfer and
the main characteristics of mechanically agitated systems (the tangential velocity).The steps encountered in industrial
production lines, food, cosmetics, pharmaceuticals, petrochemicals, cleaning products, etc ... are based on the precepts
of agitation, mechanical agitation of the fluids promotes mixing to obtain a certain degree of homogeneity of the final
product and increases the mass transfer phenomena. A hydrodynamic and mass study is needed to optimize the design of
tanks and the mobile agitation. A local (tangential velocity) and global study (the number of power) in a conventional
stirring system agitated by a straight blade (d/D = 0.5) allowed us to compare our results with the experimental
literature, a very good agreement was observed. This validation will allow us to perform simulations on two-bladed
chamfered. The velocity profile and the mass transfer are analyzed. It has been shown that the hydrodynamics and mass
transfer are modified by the effect of the chamfering of the mobile that plays a role.
A comparative analysis between the straight and the chamfered mobile is adopted.
