Cambustion gas and particle analyzers are used for both wind tunnel tracing (hydrocarbon tracer) and atmospheric gas dispersion studies (hydrocarbon tracer and particle size distribution measurements).
An intermittent or continous point source release of concentrated aerosol or gas tracer disperses under the influence of airflow, thermal gradients and surrounding obstacles. Meausurements with high frequency instruments allow resolution of variable mixing and dispersion, supporting understanding of aerodynamic behaviours in windtunnels and more complex interations in the ambient environment, with consequent human exposure to pollutants.
