喷嘴几何参数对自激吸气脉冲射流性能影响的正交试验
Orthogonal experimental on effect of geometrical parameters on self-excited inspiration pulsed jet nozzle performance
摘要
Abstract
In order to determine the geometrical parameters of the self-excited pulsed jet nozzle and the significance and importance of the order that their interactions affect its performance.The experiment on the inspiratory performance and impact property of the self-excited inspiration pulsed jet nozzle was conducted by the orthogonal experiment method,and the nozzle area ratio,relative oscillation cavity area,relative cavity length and the sensitivity of their interactions to the inspiratory performance and impact property of the device were analyzed by range analysis and variance analysis.The results show that the geometrical parameters that affect the inspiratory performance in descending order are:relative cavity length,relative oscillation cavity area,the interaction between relative oscillation cavity area and relative cavity length,the interaction between nozzle area ratio and relative oscillation cavity area, nozzle area ratio.The geometrical parameters that affect the impact property in descending order are:nozzle area ratio,relative oscillation cavity area,the interaction between of relative oscillation cavity area and relative cavity length is,relative cavity length among them.The former two contribute is much greater the nozzle impact property than the latter two verifying tests confirmed the conclusions of orthogonal experiment.关键词
