Abstract

A turbulent flow simulating that observed at high atmospheric altitudes was created in a wind tunnel. Heat was introduced to the flow in such a way as to simulate gaseous pollutant releases in the atmosphere. Hot wire anemometry with a double wire probe was used for simultaneous measurements of velocity and temperature. Suggestions for further experimental work regarding the mechanism of heat transport are also given. 1 Introduction The dispersion of gaseous pollutants released into the atmosphere at ground level is dominated by turbulence. At low altitudes ( <1.5km), it is determined by the atmospheric boundary layer flow. This is essentially three-dimensional and contains large eddies caused by thermal b
