Abstract: This study characterizes the shear layer and associated vortex shedding around an isolated submerged pebble cluster in a gravel-bed river. The approach combines flow visualization and high frequency three-dimensional ...

Abstract: The present paper describes an experimental investigation of the various parameters affecting the operation of industrial pneumatic controllers based on the jet nozzle principle. A test rig was ...

Abstract: Although a discordance in bed elevation between mainstream and tributary channels is a common feature of most river confluences, this height differential is largely ignored in many models of junction flow dynamics. Here ...

Abstract: Two series of laboratory experiments were conducted to evaluate the influence of mean flow direction and sampler size (7,6 cm aperture vs 3 cm aperture) upon the efficiency of Helley‐Smith samplers in subcritical flows. ...

Abstract: The application of pneumatic metrology to control dimensional accuracy on machined parts is based on the measurement of gas flow resistance through a restricted section formed by a jet orifice ...

Abstract: This paper studies laboratory open-channel confluences using a 3D, elliptic solution of the Reynolds-averaged Navier-Stokes equations, including a method for approximating the effects of water surface elevation patterns ...
