| 摘 要： | 研究高速巡航导弹动力装置优化问题,针对进气道结构严重影响速度的提高,为减少人工建模的工作量,以提高数值仿真分析工作效率和满足二元超声速进气道设计方案的快速评比和选型的需要,提出建立流场计算域通用的结构化分区几何模型,统一基于所构造的基准进气道模型,一次性人工划分进气道结构化计算网格,根据边界几何控制,运用网格映射和比例变换方法,编程自动化实现由基准进气道计算网格映射生成实际结构不同的系列化二元进气道计算网格。用建立的模型进行仿真。结果证明,减少了建模工作量和提高了工作效率。

| Abstract: | To reduce modeling workload,improve the efficiency of numerical simulation,and meet the needs for fast design evaluation and selection,a general geometric model of structural computational domain partition for 2-D supersonic inlet flow field is constructed.Based on baseline inlet,structural grids are created.Then,based on boundary geometric control,a serial of inlet computational grids with different structures are generated automatically from baseline grid by programming using grid mapping and proportional... |
