Abstract

Project 11C deals with the impact of surface heating in urban areas on the dispersion of contaminants in the atmosphere. + The atmospheric boundary layer is simulated in a water flume. Ground heating is applied locally reproducing the heat flux of an urban region. Fission products for which internal heat source is neglected are simulated by horizontal plumes at pHs different from the original pH of the flume. + The main results of the study concern: The characterization of the internal boundary layer downstream of the leading edge of the heated ground. The comparison of the concentration distributions of pollutants with and without surface heating. + A transposition of the results, expressed in terms of global parameters, enables information on the heat island effect due to urban regions on the dispersion of contaminants in the atmosphere to be obtained.
