From theCambridge English Corpus Miles (1950) studied the matter of the ' compressibility correction' for wings oscillating sinusoidally insubsonicflow. From theCambridge English Corpus However, this condition is not exclusively a supersonic one, since it can also be met if the ion flows are individuallysubsonic. From theCambridge English Corpus The associated variation in the (subsonic) proton speed also corresponds to a compression (up < 1), while the (subsonic) electrons are accelerated. From theCambridge English Corpus The grey zone highlights the supersonic regime, the white zone indicates thesubsonicregion. From theCambridge English Corpus Based on all the above data it appears that only the axisymmetric instability and acoustic wave modes are allowed insubsonicresonant impinging jets. From theCambridge English Corpus Thesubsoniccase (figure 12a) is asymmetric, indicating possible pressure communication across the potential core. From theCambridge English Corpus Now, close to the stagnation point the speeds aresubsonic, and all compressibility effects are due to thermal variations in the fluid properties. From theCambridge English Corpus It follows that solitons may propagate atsubsonicspeeds in a cone of obliquity. From theCambridge English Corpus Some results of an experimental investigation of forces associated with thesubsonicflow of air around a circular cylinder in a wind tunnel are presented. From theCambridge English Corpus Asubsonicwave with constant amplitude generates no sound. From theCambridge English Corpus A second set of boundary conditions consistent with the given body profile is imposed on thesubsonicside. From theCambridge English Corpus Note, however, that many of their results apply t o regions where the jet issubsonicand are then valid. From theCambridge English Corpus This, however, only applies t o thesubsoniccase. From theCambridge English Corpus However, the region that radiates noise in thesubsoniccase is far from the peak amplitude wavenumber.
