Abstract
Existence of a collateral flowfield in the inner boundary layer region very close to the wall is probed. The near-wall region of a three-dimensional turbulent air boundary layer relaxing in a nominally zero external pressure gradient behind a transverse hump faired into the sidewall of a low-speed wind tunnel. Hot-wire data and polar plots of mean velocity profile are exhibited. Difficulties in measurement of near-wall skewed flows are indicated. Possible crossflow reversal triggered by slight lateral adverse pressure gradients and producing a collateral layer are considered; in their absence, a noncollateral flowfield in the neighborhood of the wall is found consistent with the equations of motion.
