Abstract

This paper reports on hot-wire measurements of a heated air jet issuing in a cross wind. The flow studied simulates outfalls and accidental pollutant releases in the atmosphere. All statistical parameters of the simulated pollutant concentration were found to be self-similar. Turbulent transport terms of the flow field were directly measured, providing support to numerical modellers. In this work, emphasis is put on the development of simple relationships, describing the pollutant trajectory and dilution. 1 Introduction In everyday practice, air pollutants issue in the atmosphere from outfalls (e.g., stacks). Occasionally, accidental releases of pollutants (e.g., liquefied gases stored in pressurised
