WIND TUNNEL MODELING OF VELOCITY PROFILES OF THE ATMOSPHERIC SURFACE LAYER.

Abstract

Many of the conditions commonly assumed for studies of the atmospheric boundary layer can be reproduced in a low-speed wind tunnel. Valid criteria are needed to determine similarity of flows obtained in wind tunnel experiments and natural flows. Reasonably good general indications are available from comparison of normalized velocity profiles from wind tunnel and field observations. In this paper, a dimensionless modeling parameter, K, is examined. This is a point parameter which is a function of both the local mean velocity and local turbulent shear stress. Preliminary results indicate that K has merit as a modeling parameter for the limited class of flows discussed. (Author)
