Wall-Wake Flows Downstream of a Sphere Placed on a Plane Rough Wall
- S. Dey, Sankar Sarkar, S. Bose, S. Tait, O. Castro-Orgaz
- Physics, Engineering
- 1 October 2011
The time-averaged characteristics of turbulent wall-wake flows downstream of a sphere placed on a rough wall are studied. The profiles of the defect of streamwise velocity, Reynolds shear stress, and…
Scale effects of round-crested weir flow
- O. Castro-Orgaz, W. Hager

- 3 September 2014
ABSTRACT Scale effects of round-crested weir flow originate from viscosity and surface tension. No general weir flow equation accounting for these is available in the literature. In this work an…
Classical hydraulic jump: basic flow features
- O. Castro-Orgaz, W. Hager

The dynamics of free surface flow is characterised by the so-called Froude number F, whose value F = 1 separates subcritical (F < 1) and supercritical (F > 1) flows. The transition from F < 1 to F >…
Subcritical Side-Weir Flow at High Lateral Discharge

[1] Is the von Karman constant affected by sediment suspension? The presence of suspended sediment in channels and fluvial streams has been known for decades to affect turbulence transfer mechanism…
Curvilinear flow over round-crested weirs
- O. Castro-Orgaz
- Engineering, Environmental Science
- 1 July 2008
Curvilinear flow over round-crested weirs is a problem of both theoretical and practical significance because of its presence in overflow structures used in dam engineering, and its connection to the…
