IAWE Aylesbury Comparative Experiment — Preliminary results of wind tunnel comparisons

Abstract The Aylesbury Comparative Experiment seeks to validate techniques for modelling low-rise buildings at large scale factors in wind tunnels by comparing the results from a 1: 100 scale standard model in wind tunnels around the world. In this paper a summary of the preliminary results from the first 11 laboratories is presented. Linear regression analysis shows that the regression scatter is quite small, but there are consistent differences between laboratories in zero level and gain, each in the range ± 15% . These are attributed to differences in the method of acquisition and the position of the reference static and dynamic pressures.
