The Different Impact of a Half-Separated Gravel and Vegetated Bed in Open Channels
(2015)This paper investigates the different impact of a half-separated gravel and vegetated bed in open channels. This experimental investigation is based on the 2D Particle Image Velocimetry (PIV) method, which allows data ... -
Experimental and Numerical Study of Turbulent Flow in Open Channels with Impermeable and Porous Bed
(2016)In order to experimentally and numerically investigate turbulent flow in an open channel with porous (vegetated) and impermeable bed 2D Particle Image Velocimetry (PIV) and a Computational Fluid Dynamical (CFD) model were ... -
The impact of the instrument in velocity measurements in an open channel with a porous bed
(2017)In this study, the impact of the type of instrument used [hot-film anemometry and particle image velocimetry (PIV)] in velocity measurements in open channels with a porous bed is investigated. Individual experiments using ... -
Influence of permeable bed and channel width on turbulent characteristics in inclined open channel flows
(2017)For the investigation of the influence of the kind of the different permeable bed and channel width in inclined open channels, a series of laboratory experiments were performed. Experiments were conducted in two channels ... -
Similarities and Differences between Hot-film Anemometry and Particle Image Velocimetry in Open Channels
(2016)In this study a comparison between hot-film anemometry and Particle Image Velocimetry (PIV) measurements in open channels is investigated. For this reason individual experiments with these two methods were conducted. ... -
Transition from permeable to impermeable beds and vice versa in open channels: Effects on the velocity distribution of turbulent flow
(2014)This study investigates the impact of permeable to impermeable (and vice versa) bed transition on the velocity distribution of turbulent flow in an open channel. This experimental investigation is based on the 2D Particle ... -
Velocity profiles in a random porous bed
(2021)In this study the velocity distribution of the fluid flow through and over a random porous bed is investigated. The different porous bed and the different porosity influence significantly the form of the velocity profiles. ...
