generalized newtonian fluid and numerical simulations examined the mixing behavior with newtonian and non-newtonian fluids in simplified geometries of twin-screw mixers [12–14]. moreover, the influence of the mixer geometry and operating conditions were studied [15].

the mechanical properties of hardened concrete increase if less water is used in the concrete mix design, however reducing the water-to-cement ratio may decrease the ease of mixing and application. to avoid these undesired effects, superplasticizers are typically added to decrease the apparent yield stress and the viscosity of the fresh paste.

with a further increase in gas rate, the larger gas bubbles become unstable and collapse, resulting in churn flow, a highly turbulent flow pattern with both phases dipsersed. churn flow is characterized by oscillatory, up and down motions of the liquid.
