Abstract

When a person is in a unidirectional airflow and the contaminant source is wihtin the wake region, high exposure can occur. This work studied the effects of freestream velocity and convective heat release rate on the exposure both experimentally and numerically. The buoyant forces became important with low air velocities. The CFD calculations corresponded to the experiments reasonably well.
