摘要: The effects of boundary permeability and undulation in turbulent pipe flow are observed an air conduit lined with a granular permeable material. Boundary pressure, mean velocity distribution, longitudinal turbulence intensity were measured at several sections along the sinusoidal boundary. pressure shows phase shift relative to wave form magnitude similar that found from simple potential analysis. distributions differ drastically those impervious wavy pipes, implying important effect aspiration porous lee form. observations show dramatically alters structure as compared pipe. In pipe, zone high develops expands central portion For turbulenc...
