SPH Method for Vertical Mixing Process of the Solid Propellant Slurry
立式混合机内桨叶的行星运动可有效促进物料不同组分间的分散循环和均质分布,故已应用于固体推进剂药浆的制备过程.然而,混合机内的复杂界面及其运动导致药浆内部的混合机理与流变特性难以采用传统的方法进行研究.针对层流流动下推进剂药浆与桨叶耦合过程,基于光滑粒子法(Smoothed Particle Hydrodynamics,SPH),连续体被离散为若干携带物理量的守恒质点.结合Herschel-Bulkley(HB)本构模型,发展了适用于非牛顿流体状态…查看全部>>
The planetary motion of impeller in the vertical mixer can effectively promote the dispersed circulation and homoge-neous distribution of different material components,which has been employed in the preparation procedure of solid propellant slurry.However,the mixer involves complex interfaces and motions that it is difficult to study the mixing mechanism and rheo-logical property of slurries by traditional methods.Based on the smoothed particle hydrodynamics…查看全部>>
