Air core and roping in hydrocyclones

Abstract In this work we develop an equation for the air core diameter in a hydrocyclone in terms of geometrical and operational parameters, based in a phenomenological equation which we derived previously. Using this equation the air core diameter in a 6 inch hydrocyclone was calculated and from this result the discharge type, spray or roping, could be predicted accurately for the experiments performed by Plitt et al. and by Bustamante.
