Abstract:
Based in the analysis of suspension mechanism,this paper derived the suspesion condition from the depositional characteristics of single cuttings particle in non-homogeneous turbulence fiels.Which is described by the annular hydraulics and load-bed properties of cuttings,took into consideration the effects of particle shapes and cuttings concentration,and established the formula of the slip velocity of non-globe cuttings damped setting,thus evaluated the macroscopic laws of cuttings-suspension transportation under the given flow in eccentric annulus.
Key words: Annulus flow, Turbulent flow, suspened particle, cuttings, suspension transportation
