The.e.fe.ts of various parame.e.s, name.y the.initial radius, initial radial ve.ocity, initial angular ve.ocity, and drag-to-ine.tia ratio, on the.non-dime.sional ve.ocity profile. and particle.position distribution are.conside.e.. The.re.ults show that the.radial ve.ocity incre.se. ove. time.while.the.angular ve.ocity de.re.se., and that an incre.se.in the.initial radial ve.ocity incre.se. the.particle.radial distance.and angular ve.ocity but de.re.se. the.radial ve.ocity profile.
