Webbump: [noun] a relatively abrupt convexity or protuberance on a surface: such as. a swelling of tissue. a cranial protuberance. WebThe mean flow and Reynolds stresses for the lowest bump are in good agreement with experimental data. The flow encounters a favourable pressure gradient over the windward side of the bump, but does not relaminarize, as is evident from near-wall fluctuations. A patch of high turbulent kinetic energy forms in the lee of the bump and extends into ...
