Design and modelling of hydrocyclones and hydrocyclone networks for fine particle processing

Modeling fluid behavior and droplet interactions during liquid–liquid separation in hydrocyclones

“…The simulation of the high-turbulent cyclone vortices requires the numerical solution of the basic equations of fluid dynamics combined with an adequate turbulence model. Turbulence effects are often characterized in a simplified manner by using the Prandtl mixing length model (Bloor and Ingham, 1975a,b;Pericleous and Rhodes, 1986;Davidson, 1988;Rajamani, 1988a,b, 1991;Rajamani and Devulapalli, 1994) or empirically modified k--models Roldán-Villasana et al, 1993;Malhotra et al, 1994;Dai et al, 1999;He et al, 1999;Statie et al, 2001Statie et al, , 2002Salcudean et al, 2003;Yang et al 2004). The Prandtl mixing length model relies on the basic assumption of turbulent equilibrium so the simulation results match the real flow conditions in a qualitative manner but there is a lack concerning a quantitative comparison between simulation results and experimental data.…”

Factorial design and statistical analysis of smectite clay treatment by hydrocyclone

“…Few studies on modeling, simulation and optimization of response variables in relation to the average diameter of clay particles are found in the literature. Villasana et al [23] studied the planning and modeling of hydrocyclone in relation to the pressure parameters and flow rate of an integrated hydrocyclone system. Schneider and Neege [24] examined the hydrocyclone simulation for the treatment of non-metallic minerals.…”
