PIV Measurement and Numerical Simulation of the Airflow Field in a Road Vehicle HVAC Splitter Duct 2001-01-1761
The analysis of airflow in a road vehicle HVAC splitter duct is complicated by the cross sectional variations and abrupt changes in airflow direction. In this study, the complex three-dimensional turbulent airflow found in a generic automotive HVAC splitter duct is investigated experimentally and computationally. An optical anemometer is used to acquire the experimental data within the HVAC duct. The results are then used to validate and tune a Computational Fluid Dynamics (CFD) numerical model.
