Experimentally modelling dispersive scalar fluxes in a 3D printed urban environment using a water tunnel
Experimentally modelling dispersive scalar fluxes in a 3D printed urban environment using a water tunnel
The modelling of urban air pollution requires an understanding of the turbulent processes involved. Measuring these processes requires a high-fidelity experimental study, and this project aims to provide that. An investigation into scalar dispersion over a 3D-printed model of the City of Southampton was carried out. This 1000:1 scale model was created to represent 1km2 of Southampton’s city centre. Experimentally measuring turbulent scalar fluxes is challenging as it requires both concentration and velocity measurements in the same place, and at the same time. Particle image velocimetry (PIV) and planar laser induced fluorescence (PLIF) were used to measure full fields of these turbulent scalar fluxes. Measurements were carried out in streamwise-vertical and wall-parallel planes to create a detailed map of concentration and velocity data for a case in which a plume from a point source was introduced upstream of this model.

Abstract
The modelling of urban air pollution requires an understanding of the turbulent processes involved. Measuring these processes requires a high-fidelity experimental study, and this project aims to provide that. An investigation into scalar dispersion over a 3D-printed model of the City of Southampton was carried out. This 1000:1 scale model was created to represent 1km2 of Southampton’s city centre. Experimentally measuring turbulent scalar fluxes is challenging as it requires both concentration and velocity measurements in the same place, and at the same time. Particle image velocimetry (PIV) and planar laser induced fluorescence (PLIF) were used to measure full fields of these turbulent scalar fluxes. Measurements were carried out in streamwise-vertical and wall-parallel planes to create a detailed map of concentration and velocity data for a case in which a plume from a point source was introduced upstream of this model.
