摘　　要：以油辣椒固液混合多相流的灌装过程作为研究对象,采用流体力学仿真软件Fluent软件对其灌装进行数值模拟仿真,主要研究在灌装机构中物料所占体积分数不同,对灌装过程中的流场分布的影响。数值模拟仿真结果表明,在整个灌装机构中,不同菜籽油体积分数的油辣椒固液混合多相流,随着菜籽油体积分数的增加,混合流体的流动性有所改善,密度均匀性变好,高密度和低密度区域明显减少,菜籽油增加了混合流体的流动性,特别是管道内壁,减少了高密度聚集,为油辣椒的灌装过程研究提供理论依据。Taking the filling process of solid-liquid mixed multi-phase flow of oil pepper as the research object,this paper used Fluent software to carry out numerical simulation of its filling,mainly to study the effect of different volume fraction of the material in the filling mechanism on the flow field distribution in the filling process.The numerical simulation results showed that:In the whole filling body,different rapeseed oil volume fraction oil pepper solid-liquid mixed multiphase flow,with the increase of rapeseed oil volume fraction,hybrid fluid improved liquid,density uniformity,high density and low density area decreased significantly,canola oil increased the liquidity of mixed fluid,especially the pipe wall,the less dense aggregation.It provided a theoretical basis for the study of filling process of oil pepper.
