Abstract
This paper presents results from experiments conducted in the water channel to investigate turbulence and dispersion around an isolated, cubic obstacle in a neutrally-stratified boundary layer. Pollutant emission is simulated by means of three point sources, located in the vicinity of the cube. Velocity and concentration measurements are carried out at evenly spaced vertical planes, so as to reconstruct the three-dimensional pollutant plume. Here, preliminary results referred to the vertical section passing through the middle plane of the cube are presented. From the instantaneous values of the pollutant concentration, high-spatial resolution maps of mean, variance, intensity and skewness factor of the concentration field have been determined.File | Size | Format | |
