摘要/Abstract

摘要：

基于离散元法和计算流体动力学方法, 设计一种流固耦合及流动过程分析软件, 实现了与三维计算机辅助设计软件的集成, 从而开发出一种集设计与性能分析评价为一体的新型计算机辅助工程软件--AgriDEM, 并通过实例验证了该软件的可行性和有效性.

关键词: 离散元法, 计算流体动力学, 计算机辅助设计, 计算机辅助工程, 优化设计

Abstract:

Based on the discrete element method and computational fluid dynamics method, the software for the analysis of dense fluidsolid interaction and the flow was developed, and the integration with threedimensional computer aided design software was achieved, then a new computer aided engineering softwareAgriDEM with design and analysis and evaluation of the performance was developed. The correctness and validity of the software were verified by some examples.

Key words: discrete element method (DEM), computational fluid dynamics (CFD), computer aided design (CAD), computer aided engineering (CAE), optimal design
