Developing flow in skimming flow regime on embankment stepped spillways

Journal of Hydraulic Research, 2011
In hydraulic engineering, stepped spillways are effective structures in regard to both energy dissipation and re-aeration processes. It is well known that flow depths and flow velocities generally depend on the spillway geometry in terms of slope and step-induced macro-roughness height on the one hand and the discharge on the other hand.

Flow properties of freeze-concentrated skim milk

Journal of Food Engineering, 1997
Abstract The flow properties of freeze-concentrated skim milk, determined with a concentric cylinder viscometer, were well described by the simple power-law rheological model over the temperature range from — 3.4 to + 20 °C. High-total-solids freeze-concentrated skim milk (35–40% total solids) exhibited non-Newtonian behaviour, while lower ...

OIL LAYER FLOW AROUND SKIMMING VESSELS

International Oil Spill Conference Proceedings, 1989
ABSTRACT The flow of an oil layer around an advancing skimming vessel was investigated theoretically on the following assumptions: (1) the oil layer is so thin that the velocity distribution is uniform over the depth; (2) there is no shear and tension at the oil-water interface; and (3) the density difference between oil and water is so ...

Study on the Flow Behavior in the Low Flow Region of Skim Milk Solutions [PDF]

広島大学生物生産学部紀要, 1980
The flow equations of liquid foods are important for the designing and controlling of various apparatuses. In this paper, we studied the flow behavior of skim milk solutions under low concentration at various temperatures. For measuring the flow behavior, we used a capillary tube viscometer operated under various pressures.

Flow Characteristics of Skimming Flows in Stepped Channels

2006
Ohtsu et al. must be congratulated for their systematic study of skimming flows on stepped channels with different slopes and step heights. Their experimental data provide a solid database that might lead to better and improved design criteria. Important outcomes include some estimate of friction factors for skimming flows and a design flow chart for ...

Skimming of microspheres in vitro: implications for measurement of intrarenal blood flow

American Journal of Physiology-Heart and Circulatory Physiology, 1981
Skimming could result in erroneous estimation of renal cortical blood flow distribution as measured by microspheres. Skimming of microspheres with diameters 10, 12, and 15 micrometers and red blood cells was therefore studied in a model in which an interlobular artery and its first arteriolar branch were simulated by 80- and 30-micrometers-wide slits ...

Simulations on Skimming Flow over a Vertical Drop Pool

Journal of Engineering Mechanics, 2014
AbstractThe installation of a drop pool in an open channel is aimed to dissipate the flow energy that diminishes the destruction of the downstream channel. Previous studies have been conducted experimentally on the hydraulic properties for flow over the pools. The numerical simulations based on the Reynolds average Navier-Stokes (RANS) equation and the

ENERGY DISSIPATION IN SKIMMING FLOW OVER STEPPED SPILLWAYS

ISH Journal of Hydraulic Engineering, 1996
ABSTRACT Stepped spillways are provided to reduce the size of stilling basins with the view of reducing the overall cost of spillway and energy dissipation device. The characteristics of flow over stepped spillway are still not well known. This paper presents an equation for estimation of energy loss on stepped spillway for skimming flow regime, which ...
