Influence factors of pressure loss in pipeline transportation of paste slurry
工程科学学报, 2015 A new pipe loop test platform was built to study the influence factors and levels of pressure loss in slurry pipe transportation. The influences of pipe inner-diameter, flow velocity, slurry concentration and particle size on the pressure loss were ...

Refinement of turbulent flow velocity characteristics [PDF]
Инженерно-строительный журнал, 2013 The basic laws of Prandtl semi-empirical turbulence theory were analyzed in the article. It was shown, that the Prandtl – Nikuradse logarithmic distribution of velocities are not strictly universal. The change of the first and second turbulence constants

Measurement of unsteady velocity flow field of pulsating flow
EPJ Web of Conferences, 2016 This paper describes an investigation of the commercial synthetic jet actuator “SynJet ZFlow 90 Outdoor Cooler” (Nuventix). The velocity flow field was investigated using the thermoanemometry method in the constant temperature mode.

Simulating river flow velocity on global scale [PDF]
Advances in Geosciences, 2005 Flow velocity in rivers has a major impact on residence time of water and thus on high and low water as well as on water quality. For global scale hydrological modeling only very limited information is available for simulating flow velocity. Based on the

Velocity Correlations in Dense Granular Flows [PDF]
Physical Review Letters, 2004 Velocity fluctuations of grains flowing down a rough inclined plane are experimentally studied. The grains at the free surface exhibit fluctuating motions, which are correlated over few grains diameters. The characteristic correlation length is shown to depend on the inclination of the plane and not on the thickness of the flowing layer.
