However, the region that radiates noise in the subsonic case is far from the peak amplitude wavenumber.
This, however, only applies t o the subsonic case.
Note, however, that many of their results apply t o regions where the jet is subsonic and are then valid.
A second set of boundary conditions consistent with the given body profile is imposed on the subsonic side.
A subsonic wave with constant amplitude generates no sound.
Some results of an experimental investigation of forces associated with the subsonic flow of air around a circular cylinder in a wind tunnel are presented.
It follows that solitons may propagate at subsonic speeds in a cone of obliquity.
Now, close to the stagnation point the speeds are subsonic, and all compressibility effects are due to thermal variations in the fluid properties.
