The objective of this experiment was to determine a relationship between the pressure distribution on the generic front fascia shape of a new vehicle and the corresponding ram correlation coefficients . For this purpose , a simple theoretical model is presented which establishes the expected relationships between the pressure distribution and ram correlation coefficients . An aspirated cylinder in cross flow was taken as an idealized representation of a vehicle front end and the experimental investigation was carried out in the Texas Tech University Wind Tunnel . Results of the measurements are in agreement with the theoretical expectations for openings which are located at or near the stagnation point or at the location of a pressure coefficient equal to one on the front of the model . For openings significantly further from the stagnation point or close to the location of a zero pressure coefficient on the model , the experimentally determined ram correlation coefficients exhibit less agreement with the theoretical expectations |
