Anatomy of a laminar starting thermal plume at high Prandtl number
(2011)We present an experimental study of the dynamics of a plume generated from a small heat source in a high Prandtl number fluid with a strongly temperature-dependent viscosity. The velocity field was determined with particle ... -
Effects of different porous beds on turbulent characteristics in an open channel above the porous bed
(2017)An analysis of the turbulent characteristics of the flow in an open channel with horizontal porous beds using two-dimensional (2D) Particle Image Velocimetry (PIV) is presented. Hydraulic characteristics such as velocity ... -
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. ... -
