Abstract: Considerable effort has been devoted to the control of natural laminar-turbulent transition using various techniques, e.g., Refs. 1234. Out of all the techniques tested, suction has been found ...

Abstract: Measurements of the flow field downstream of an upstanding step change in surface roughness are presented. The roughness has the form of two-dimensional square section ribs placed transversely ...

Abstract: Measurements of wall shear stress fluctuations have been made in a fully developed turbulent duct flow, using a surface heat transfer gauge. Measurements, made over a moderate Reynolds number ...

Abstract: Mean velocity and turbulence intensity measurements have been made in a fully developed turbulent boundary layer over a d-type surface roughness. This roughness is characterised by regular ...

Abstract: The behavior of a cylinder wake in a weak uniformly sheared external stream is studied. It is found that the departure of the wake from the linear velocity distribution of the external flow ...

Abstract: The mean velocity profile across a fully developed turbulent duct flow is obtained from an eddy viscosity relation combined with an empirical outer region wake function. Results are in good ...

Abstract: This review considers theoretical and experimental knowledge of rough-wall turbulent boundary layers, drawing from both laboratory and atmospheric data. The former apply mainly to the region above ...
