2015-3-7Conclusions A numerical model HAAS for the design of axial hydrocyclone geometries has been developed. It has been used to develop the DelftCyclone de-oiling separator. HAAS results have been compared with those from laboratory experiments, and with those from detailed numerical simulations using Fluent, V6.0.12.
2010-9-23Witwatersrand were used to investigate the effect of design parameters on the flotation of pyrite in an air-sparged hydrocyclone ASH. In the ASH, air is sparged radially through the porous cylinder and dispersed by the high velocity of slurry in swirl flow countercurrent to the rising froth phase.
2017-10-13design velocities determined by the different air densities were used for the tests. Experimental results indicate that optimal cyclone design velocities, which are 16 ms 3200 ftmin for 1D3D cyclones and 15 ms 3000 ftmin for 2D2D cyclones, should be determined based on standard air density. It is important to consider the air density effect

2014-4-4classify the particles. There are various design parameters of hydrocyclone which are as follows Cone angle For design purpose, 20 0 and 26 0 cone angles were chosen. Arterburn 1976 reported that the larger the hydrocyclone diameter, the coarser the separation. The included angle of the cone section is normally between 10 0 and 20 0. Cone ...
2010-12-22that the flow field characteristics inside the hydrocyclone with solid core became more suitable for the separation process, i.e., by replac-ing the air core with solid core, the hydrocyclone separation perfor-mance improved effectively. Shin et al. 9 reported the design and performance evaluation of a hydrocyclone to remove fine particles.
2019-9-1Optimal parameters for efficient separation have been determined for the density of fluid, diameter of the spigot, and diameter of the vortex finder. The principal contribution of this paper is that key parameters for design optimization of the hydro-cyclone have been investigated.
Obtaining scale-up parameters allows making rapid predictions concerning a hydrocyclone design and performance. Therefore, to extend the present results of the micro-hydrocyclone to any hydrocyclone from the same family same geometry proportions, the constant K of a semi-theoretical design equation is calculated as follows Svarovsky, 1984 .
