Samenvatting
Wind tunnel test data on a 1-16th scale car-caravan combination show the influence of various caravan design features on the overall drag and lift of the combination. General conclusions from this were that: 1) rounding the forward edges; 2) sloping the forward face rearwards from the bottom; 3) reducing the gap, and 4) using guide vanes down the rear vertical edges, would contribute to reduced drag.
