Retrospective Glance of a Boundary Layer Wind Tunnel Experiment 25 Years Ago

摘要

This report is a reprint of the contents of the paper ''A type of wind tunnel for simulating phenomena in the natural wind'', AGARD-report No. 308, 1960, and is issued on the occasion of the 25th anniversary of the experiments described. They were the first experiments in Denmark that modelled part of a town, Copenhagen, in a boundary layer wind tunnel designed for that specific task with the aim of investigating the distribution over the city of the emmission from a high factory chimney stack. At the time, 1959, the common interest in environmental problems was not very pronounced. However, the TUBORG brewery insisted on documentation for the selection of the height of a new chimney stack at the factory, sufficiently high to avoid causing any nuisance to the population in the surroundings, and so took the initiative of having the experiments realized.
