摘要: 本稳从单颗球形颗粒在非均匀紊动流场中的沉降特性出发,根据悬浮机理的分析得到了由环空流场水力及岩屑层移床特性所表征的悬浮条件,井考虑颗粒形状及其浓度效应等因素的影响,最后得到了非球形颗粒阻尼沉降的速度公式。由此评价在给定流场条件下岩屑颗粒悬浮运移的群体特性。
关键词: 环形空间流动, 紊流, 悬浮颗粒, 岩屑, 悬浮搬运
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
