【摘要】 本文用标准稳态K-ε双方程二阶湍流封闭模型模拟流场,在全面考虑固体颗粒受力情况的基础上,用跟踪颗粒运动的Lagrangian方法描述球形固体颗粒运动,数值求解了紊流场和颗粒运动轨迹。数值计算结果与实验结果相比是令人满意的。更多还原

【Abstract】 Adopting the standard K-ε two equation model and considering all the forces acted on the solid particle, the turbulent flow field and particle movement trajectory are numerically solved by SIMPLE procedure and the Lagrangian approach respectivly in this paper. The calculated results of the distribution of concentration are close agreement with measurements.更多还原
