Průchod posivního polutentu idealizovanou městskou zástavbou

The regular obstacle array of the Mock Urban Setting Test (MUST) field site in the Utah West Desert has been replicated in the large boundary layer wind tunnel at Hamburg University. Dispersion from a point source within an idealised urban canopy for an oblique wind direction was a main focus of the wind tunel measurements. Two different methods were used to estimate the travelling time of a passive tracer through the array. The first evident method was based on a measured instantaneous behaviour of the plume while switching on and off thepassive pullant source; the second one used the spatial concentration correlation coefficients obtained from the simultaneous measurement at two positions. Different travelling time behaviour for the points situated along and perpendicular to the street canyons has been detected.
