摘要
颗粒流广泛存在于工农业生产中,颗粒物料与机械装备的接触关系和动态响应特性直接关系到生产作业性能和工作效率,因而对颗粒物料流体动力学特性的研究意义重大。从理论分析、实测试验和数值模拟三个方面对颗粒物料流体动力学特性的研究现状进行综述,并提出颗粒运动研究的未来发展趋势,推进交叉学科发展、加强理论研究、开发适用性更广的多维瞬态测试技术和精度更高的三维数值模拟方法。
Granular flow is widely available in industrial and agricultural production. The contact relation and dynamic response of granular materials and mechanical equipment directly affect the production performance and working efficiency, which have great significance for studying fluid dynamic characteristics of granular materials. The research status was summarized from three aspects, in- cluding theory analysis, actual experiment and numerical simulation. Hence, the development tendency of granular flow research was proposed, such as promote the interdisciplinary development, strengthen the theory research, and develop the multidimensional tran- sient test technology with wider applicability and the three-dimensional numerical simulation method with higher precision.
