Drag Measurement Through Wake Analysis

<div class="htmlview paragraph">Measurements are presented showing the influence of the trunk length of a road vehicle on drag coefficient. The experiments were made in the “Politecnico di Torino” wind tunnel on a 1/5 scale model. Data from balance measurements, body-surface pressure and wake flow surveys are reported.</div> <div class="htmlview paragraph">A method is shown for correlating to the aerodynamic drag data from wake survey.</div>
