摘要
CFD数值模拟技术正迅速地成为学术研究和工程实际问题分析及设计中不可缺少的工具。然而由于计算机的限制,人们在进行数值计算时常常对所研究的问题进行简化,例如几何模型简化、物理模型简化、以及边界条件近似等,这些都会对计算结果带来一定的误差。本文将通过两个轴流压缩机的例子说明计算域和边界条件选取对数值模拟结果的影响。
CFD simulation technique has been increasingly become an indispensable tool for academic research and analysis and design of industrious practical problems. However, due to the constraint of computer capacity, the studied objects are often simplified in the geometrical model, or physical model, or boundary conditions, which will lead to a certain error in the computed results. This paper is to address the influence of computational domain and boundary condition on the numerical results, by means of two axial compressor cases.
