农业工程领域颗粒运动研究综述

Summarize of Particle Movements Research in Agricultural Engineering Realm

现代农业装备的作业对象或工作介质经常涉及到离散颗粒体或颗粒群,对相关颗粒体或颗粒群的运动研究往往涉及到颗粒碰撞、流固耦合等具体细分研究领域,其研究方式、研究手段和研究结果对现代农业工程领域相关研究工作的重要性愈加显著。本文首先对农业工程领域颗粒运动的研究手段与方法从理论分析、数值模拟和实测试验3个方面分别进行了分析和归纳,然后对国内农业工程领域各典型农业装备所涉及的颗粒运动研究现状和国外本领域的研究概况分别进行了综述,并提出了农业工程领域颗粒运动研究的未来发展趋势。

Discrete particles often become the work objects or working medium of the modern agricultural equipment.Research work of particle collisions and fluid-solid coupling is always be involved in the study of particles movement.It is show that the methods and results of these researches are more and more important to the other research work in modern agricultural engineering field.The research methods of particle movement in agricultural engineering field were respectively illuminated from these aspects like theory analysis,numerical simulation and actual experiment.Then the status of particle movement research for a few typical agricultural equipments both in China and aboard was reviewed.Finally,the development tendency of particle motion research in agricultural engineering realm was proposed.
