Quantification of Environmental Chambers by Air Velocity Mapping

Abstract

The air velocity profile of a U.S. Army Research Institute of Environment Medicine (USARIEM) test chamber was mapped using an anemometer free system. This particular chamber houses an articulated copper manikin. It was found that the air velocity within the chamber is a disparate property. Airflow patterns are significantly different chamber fan speed settings, and the practice of employing a single thermal or cup anemometer to monitor chamber air velocity, in general, is inadequate. It is recommended that the air velocity profile of a given test chamber should be mapped by techniques described in this report, for all protocol studies in which air velocity data are important, such as clothing insulation evaluation and convective heat transfer studies. Keywords: Air velocity map; Environmental chambers; Wind speed measurement.
