The feed back loop is formed by the downstream-convected large vortical structure in the shear layer and by the upstream-propagating sound pressure generated by the impingement of the jet upon the screen. Four modal stages can be cofirmed with discrete changes of dominant frequencies. Near the end of the stage the vortical structure becomes unstable, and new spectral components are produced. Thus nonlinear interaction of these components results in production of many of them. It is clear that this nonlinear interaction plays an important role in jumping to the new stage.}, pages = {21--30}, title = {円形噴流の金網への衝突時における自励振動に関する研究 : 第2報 速度変動のスペクトル成分に関する分析}, volume = {30}, year = {1996} }
