WebMay 12, 2024 · The boundary layer is the distance from the wall or surface to 99% of the maximum velocity of the fluid stream. At the surface, the velocity of the fluid is zero … Webfollowing analysis is also applicable to boundary layers on axisymmetric objects provided that the boundary layer is thin enough that local curvature terms are always negligible (i.e. !(x)R(x)!1). The boundary layer thickness grows with !(x)L<<1 x but is small with respect to the length scale of the surface . We proceed as follows:
