The boundarylayer is not approximately force-free and steep pressure drops develop inside it. Moreover, this solution appears to be exponentially small inside the inclusion and it is non-negligible only in a thin boundarylayer. To derive this differential equation we first transform (1.3) to a localized boundarylayer coordinate system centered near the spike. They considered the boundarylayer on a rotating disc and formulated the instability equations for inviscid disturbances of wavelength comparable with the boundary-layer thickness. One assumes a location for the boundarylayer and writes the variables in appropriate form relative to this location. The two-dimensional form is used because we are concerned only with a two-dimensional boundarylayer in this investigation. For a plane boundarylayer there is no readily apparent limiting transverse length. Besides the boundarylayer on a solid wall, there is another group of boundary layers. As the interaction of the stretched cross-vortex tube with the boundarylayer progresses, the vortex tube ages and gradually loses its identity. On this basis, the perturbation would be much less in water than in air, for a given temperature difference across the boundarylayer. He also ignored the boundarylayer, but assumed that the wake is closed and proved that within the closed wake, vorticity is constant. In our analysis we omitted the effects of the side-wall boundarylayer. Thus, the adiabatic compressible boundarylayer is shown to be more stable with respect to small disturbances than the incompressible one. Thus, a compressible boundarylayer is more stable than the incompressibleone. Thus, as the boundarylayer thickens because of an excessive injection rate, the hot wire moves a certain distance away from the wall. As a result, the circulation is locked in a boundarylayer near the source. The first method tried was that of a small circular cylinder momentarily introduced into the boundarylayer through a hole in the plate. The increased penetration of the d2mixing region leads to the interference of the boundarylayer a t the last measuring location. The external salinity was varied from experiment to experiment and the motion in the boundarylayer was observed. The wall to free-stream temperature ratio also plays a role in determining the characteristics of the stratified boundarylayer. In the central region, therefore, the process loses its similarity to the boundarylayer, where such an interaction cannot occur. The analogy with the classical problem of the viscous boundarylayer on a body of revolution is quite evident. In this way, small packets are shielded from the full straining potential of the boundarylayer. At station 7, the boundarylayer was 2-3 in. thick. A possible justification for a mixed velocity scaling comes from the energy balance of the boundarylayer. These examples are from corpora and from sources on the web.
