Particle Size Effects on Hydro-Cyclone Performance

The hydrocyclone has a very important roll in industrial separation. theconsideration of its behavior is very important for design. in this investigation,behavior of water flow and particles trajectory inside a hydrocyclone has beenconsidered by means of numerical and experimental methods, and results have beencompared together. to have a numerical simulation, a cfd software was used, andfor modeling flow the rng k -e model applied. finally, the effect of particle sizeon hydrocyclone performance has been studied. it was found that the grade efficiencyand number of particle that exit from underflow of the hydrocyclone is increasedwhen bigger particles is used.a series of experiments has been carried out in a laboratory with a hydrocyclone.comparison shows that, there is a good agreement between the cfd models andexperimental result.
