中文摘要: |
流体机械在轻工行业、化工行业等多种行业都得到广泛应用,通过分析CFD技术在流体机械的应用现状和发展
趋势,针对湍流模型的选择、网格的分类及使用、计算域和边界条件的确定、计算模型的验证等方面,指出了CFD技术计
算结果的可信度和二次开发应该引起重视。提出CFD技术发展方向应该是:既具有高适应、高速度、集成化和易用性的
特点,又有正确合理的V&V评价体系。 |
英文摘要: |
Fluid machineries in the light industry, chemical industry and other industries are widely used. Based on CFD
applications and development in fluid machinery, for the choice of turbulence model. the classification and use of the
grid, the determination of computational domain and boundary conditions. the validation of calculation model . etc.
CFD technique was considered to be important for the credibility and secondary development. It is concluded that the
CFD future development should be both full of high adaptability, high speed, high integration . ease of use and a
reasonable V&V evaluation system. |
