Aerodynamic Roughness Height of Gravel-covered Plains in the Puna of Argentina
The Planetary Science Journal, 2023 Plains covered by gravel-dominated desert pavement in the Puna of Argentina have an aerodynamic roughness height (or length) z _0 of ∼1 cm, likely representing a skimming flow regime above the closely spaced gravel particles. Aerodynamic roughness height

Location of inception point of alternating steps stepped spillways
Sulaimani Journal for Engineering Sciences, 2023 This study explored the effects of flat-stepped spillways having alternating steps on the inception point location. Two wooden stepped spillways with a longitudinal slope of 26.6° were constructed in a rectangular flume and tested at various discharges ...

Effect of fractional blood flow on plasma skimming in the microvasculature [PDF]
Physical Review E, 2017 Although redistribution of red blood cells at bifurcated vessels is highly dependent on flow rate, it is still challenging to quantitatively express the dependency of flow rate in plasma skimming due to nonlinear cellular interactions. We suggest a plasma skimming model that can involve the effect of fractional blood flow at each bifurcation point. For

Spatial distributions of red blood cells significantly alter local haemodynamics. [PDF]
PLoS ONE, 2014 Although bulk changes in red blood cell concentration between vessels have been well characterised, local distributions are generally overlooked. Red blood cells aggregate, deform and migrate within vessels, forming heterogeneous distributions which have

Tracking of enrofloxacin antibiotic in the making of common middle eastern cheeses
Applied Food Research, 2021 Our study aims to determine the effects of different processes (skimming, pasteurizing, curding, pressing, boiling and salting) on enrofloxacin during the making of commonly consumed Middle Eastern products (Baladi, Akkawi, Halloum, Double Cream), which ...

Study of Conveniency of Using Stepped Spillway in Roller Compacted Concrete Dams (RCCD) [PDF]
Engineering and Technology Journal, 2009 A suggested design of Bastora stepped spillway has been taken as a prototype to build a physical wooden model with scale of 1:20 (Lm/Lp). Experiments have been carried out on the model with slope of upward inclined steps of 420, 280, 140 and 00.

Flow resistance in skimming flows in stepped spillways and its modelling [PDF]
Canadian Journal of Civil Engineering, 2002 Dams and weirs must be equipped with adequate flood-release facilities for a safe dissipation of the kinetic energy of the flow. With stepped spillway design, it is essential to accurately predict the flow-resistance contribution of the steps. The authors investigate the flow resistance of skimming flows and associated form losses.

Experimental study of skimming flow on the stepped spillway in the non-aerated area using PIV [PDF]
هیدرولیکUnderstanding the flow behavior over stepped spillways has been the subject of many previous studies. Most of the studies conducted on stepped spillways have been in skimming flow conditions and the aerated parts of the spillway.
