Can the contamination of urban street sediment be used as an indicator for traffic density? A case-study in the city of Leuven, Belgium KU Leuven
The concentration, in urban street sediment, of 13 chemical elements was measured in the city of Leuven, Belgium. A total of 77 locations were sampled in pedestrian zones, streets with limited traffic, streets with much traffic, and on the ring road that has very busy traffic. The data were compared to NO2 concentrations measured by the CurieuzeNeuzen-Vlaanderen project, a large-scale study with 20,000 sampling points all over Flanders (the ...
Effect of soiling on wind-induced cooling of photovoltaic modules and consequences for electrical performance KU Leuven
© 2019 Elsevier Ltd This study investigates the effect of soiling on the cooling capacity of the wind and its consequences for the performance of photovoltaic modules. Cooling and electrical characteristics were measured on a glass-glass module for wind speeds up to 4 ms−1 and soiling levels up to 41 gm−2. Soiling can promote the cooling of photovoltaic modules and affects the influence of wind on module performance. Soiling may result in less ...
Experimentally validated CFD simulations predicting wind effects on photovoltaic modules mounted on inclined surfaces KU Leuven
© 2018 Elsevier Ltd Computational Fluid Dynamics (CFD) and wind tunnel experiments were used to study wind flow over PV modules attached to inclined surfaces. Wind velocities were investigated at various positions on a test module, for five wind speeds varying from 1 to 5 m s−1. After validation the CFD model was used to study the effects air gaps and wall cavities under the module have on the airflow over the module. Data were measured for two ...
Effect of wind on temperature patterns, electrical characteristics, and performance of building-integrated and building-applied inclined photovoltaic modules KU Leuven
© 2018 Elsevier Ltd The influence of mounting setup on the wind flow field, temperature pattern, and electrical performance of building-integrated (BIPV) and building-applied (BAPV) photovoltaic modules was investigated using wind tunnel experiments. Tests were done with an inclined 3 × 2 module for four air gap thicknesses varying from 0 cm (BIPV) to 5.5 cm (BAPV) and five freestream approaching wind speeds from 1 to 5 m s−1. Wind speed and ...
