The diffuser length should be long enough to ensure the main flow deceleration 扩压段应具有一定的长度以保证主气流减速到一定程度。
The configuration of the diffuser should be designed as a channel to allow the main flow pass through a shock train 扩压段的形状应设计成能使主气流通过系列斜激波串减速的通道。
E ) applying the inter - phase slip algorithm ipsa method to solve the set of discretized equations 对燃烧室扩压段的计算区域离散采用了贴体坐标系; e采用了ipsa算法来求解离散方程。
The effect of the diffusers was investigated for the different shapes and sizes , as well as different locations 其中,扩压段的设计非常重要,它不是孤立的,而与主流系统和引射系统密切相关。
The performance of the centrifugal compressor at different diffuser stagger angles and different inlet guide vane ( igv ) prewhirl angles are measured 摘要对扩压器进口不同安装角和进口导叶不同预旋角匹配下离心压缩机的性能进行了实验研究。
The start process of the facility for the different cases was under research in order to find the optimal configuration for the system 通过对不同几何形状的扩压段在不同安装位置进行调试,研究在风洞起动过程中整个系统流动状态的演变规律,探索扩压段的优化设计。
The experimental results show that the location of the diffuser should be close to the nozzle exit , and the shape and size of the diffuser entrance should match the nozzle exit 实验表明,扩压段应安装在距主喷管较近的位置,并具有与主喷管相匹配的入口面积和形状。
So we choose the fadw to study and design for taking the place of the solid windows of hel . a complete set of the method designing fadw is founded in this paper 由于fadw的实际流场十分复杂,特别是在射流区域和射流进入扩压器的摘要一初始阶段,因此,气动窗口的实际设计相当复杂。
When there are struts at the divergent parts of inlet , the total pressure recovery coefficients and the kinetic energy coefficients of inlet decrease , and the flow distortion index increases obviously 当进气道扩压段有侧向支柱存在时,进气道总压恢复系数和动能系数均有所降低,而流场畸变指数则显著增大。
Then a specific ventilator was chosen as an example , and by the method of objective functions , the diffusion angle of its volute was calculated and analysed to optimize the operating performance of the ventilator 并针对有具体用途(使通风机的流量达到额定值)的通风机,采用目标函数法对通风机综合性能指标最优化的扩压角进行了算例分析。
