Contribution to the Study of Fluid Flow in a Stirred Tank by Introducing Microparticles

Micro particles are today a major technological and economic issue. They enable very promising innovations in many fundamental areas such as: health, energy or industry. Despite the numerous studies devoted to hydrodynamics in agitated tanks, there is still a glaring lack of information on the temporal evolution of fluid flow properties. The knowledge of this dependence has been often crucial, for example, in the food, chemical, biochemical or petrochemical industry is carried out in tanks or in mechanically agitated reactors. The micro particles are colloidal solutions composed of particles of micrometric size suspended in a liquid. Their astonishing thermal properties have been the subject of intense investigation during the last decade. It is proposed in this work to study the influence of the concentration of micro particles (al2o3, cuo, etc.) Dispersed in a base fluid on the hydrodynamic fields of fluid in flat-bottomed cylindrical and non-quenched fluid provided with a stirrer. Anchor type was undertaken by numerical simulation using the fluent cfd 6.2.13 based on the finite volume discretization method of the navier stokes equations (uvp) equations and the energy equation. We aim at a synthesis of the simulated system by comparing the power consumed by the micro particle technique.
