“…Using computational fluid dynamics (CFD) simulations, substantial research effort has been undertaken to link flow parameters to mixing characteristics (Arcoumanis et al, 1990;Houcine et al, 1996;Corriveau and Baines, 1997;Moin, 2002;Stefani et al, 2006;Hwu, 2008, Pianet andArquis, 2008;Pirrò and Quadrio, 2008;Driss et al, 2010, Liu et al, 2011. Indeed, Vazquez and Williams (1995) used integral equation approach to investigate the influence of tank walls in a narrow tank. Kchaou et al (2008) improved the control volume discretization method to resolve the Naviers-Stokes equations in conjunction with the standard k-ε turbulence model, in order to study the hydrodynamic structure of a stirred vessel generated by a flat-blade turbine and a pitched-blade turbine.…”
