The analysis of airflow in an automotive HVAC cowl box is complicated by the cross sectional variations and abrupt changes in airflow direction. In this study, the complex three-dimensional turbulent flow found in a generic road vehicle cowl box is investigated experimentally and computationally. An optical anemometer is used to acquire the experimental data within a white metal sheet of a cowl box. The results are then used to validate and tune a Computational Fluid Dynamics (CFD) numerical cowl model.
