Nearly 95% of the energy in the stirred reactor maintains the symmetrical flow field structure
formed by fluid rotation, which reduces the efficiency of fluid transfer. In this paper, a dual …

Fractal perforating impeller was introduced to minimize the stagnation zone and enlarge the
well-mixed zone for the mixing process of shear-thinning fluids with yield stress in a stirred …

The power consumption in stirred tanks is a key parameter to determine the efficiency of a
rotating impeller. This parameter is highly related to the viscous forces of the working fluid …

To reduce the power consumption and improve the mixing performance in stirred tanks, two
improved disc turbines namely swept-back parabolic disc turbine (SPDT) and staggered fan …

Several industrial fields require mixing and mechanical agitation processes. This operation
is mainly used to enhance heat and mass transfer inside stirred tank systems and improve …

The Rayleigh-Bénard instability phenomenon corresponds to the unstable state in which
there is a horizontal layer of an expandable fluid subjected to a temperature gradient. The …
