ug ger , ▁a ▁character ▁from ▁a ▁poem ▁by ▁T . ▁S . ▁Eli ot ▁and ▁who ▁appears ▁in ▁the ▁musical ▁C ats ▁ ▁T ug ger , ▁a ▁character ▁from ▁South ▁Park ▁episode ▁The ▁New ▁Ter rance ▁and ▁Phill ip ▁Movie ▁Tra iler ▁ ▁See ▁also : ▁▁ ▁Co at - t ug ger <0x0A> </s> ▁A ▁hydro cy clone ▁( o ften ▁referred ▁to ▁by ▁the ▁short ened ▁form ▁cy clone ) ▁is ▁a ▁device ▁to ▁class ify , ▁separate ▁or ▁sort ▁particles ▁in ▁a ▁liquid ▁susp ension ▁based ▁on ▁the ▁ratio ▁of ▁their ▁cent rip etal ▁force ▁to ▁fluid ▁resistance . ▁This ▁ratio ▁is ▁high ▁for ▁dense ▁( where ▁separation ▁by ▁density ▁is ▁required ) ▁and ▁co arse ▁( where ▁separation ▁by ▁size ▁is ▁required ) ▁particles , ▁and ▁low ▁for ▁light ▁and ▁fine ▁particles . ▁H ydro cy cl ones ▁also ▁find ▁application ▁in ▁the ▁separation ▁of ▁liqu ids ▁of ▁different ▁dens ities . ▁ ▁A ▁different ▁description : ▁A ▁hydro cy clone ▁is ▁a ▁mechanical ▁device ▁designed ▁to ▁reduce ▁or ▁increase ▁the ▁concentration ▁of ▁a ▁dispers ed ▁phase , ▁solid , ▁liquid ▁or ▁gas ▁of ▁different ▁density , ▁by ▁means ▁of ▁cent rip etal ▁forces ▁or ▁cent rif ug al ▁forces ▁within ▁a ▁vor tex . ▁ ▁The ▁mixture ▁is ▁inject ed ▁into ▁the ▁hydro cy clone ▁in ▁such ▁a ▁way ▁as ▁to ▁create ▁the ▁vor tex ▁and , ▁depending ▁upon ▁the ▁relative ▁dens ities ▁of ▁the ▁two ▁phases , ▁the ▁cent rif ug al ▁acceleration ▁will ▁cause
