| 内容記述 | The inviscid, compressible, swirling flow through a slightly deformed tube or around a slender body placed on the tube axis is analyzed by means of the small perturbation method. The solution is obtained to consist of a particular solution and the eigensolutions. The eigensolutions together with the eigenvalues are evaluated for various set of the tangential and axial flow Mach numbers (M_t and M_a). The neutral curves, on which the eigenvalues vanish, are presented in the M_a-M_t diagram. These curves which characterize the mode of wave disturbances are found to lie on only the subsonic region (M_a<1) and to indicate a larger deviation from the incompressible ones for higher subsonic region. As for the actual flow phenomena, we are concerned with specific geometry of the walls or bodies, for which the particular solution has simple analytic expressions; that is, a quadratic or sinusoidal wall and an oval- or spindle-shape body. For these specific geometries, the critical curves, on which no solution satisfies the tangency condition so that the flow cannot go around the wall or body, are shown in the M_a-M_t diagram. To demonstrate the variation in wave-and flow modes, the streamlines around a spindle-shape body are depicted for various set of M_a and M_t, and a contrast between the subsonic and supersonic cases is exhibited. | |||||||
