Abstract
Sacling rules are developed for the design of experiments and choice of appropriate particles to model snow drifting on buildings in a boundary-layer wind tunnel. Several model buildings with two-level flat roofs were studied in the tunnel. The length-to-height ratios of the buildings varied from 1.0 to 10.0 and the lengths of lower roofs varied from 1.3 to 5 times the heights to the upper levels. A three-dimensional traversing mechanism holding a depth-marker was used for collecting “snow” depths after each test. Two flat-roofed buildings in Ottawa, Canada, were selected for comparison of wind tunnel with full-scale measurements. The discrepancy between results of full-scale and model-scale testing is due in part to dissimilar running conditions: the changes in wind directions could not be followed because the model buildings were too long to be rotated fully in the wind tunnel. There are enough similarities between model and full-scale snow depths to indicate that further investigation with a larger wind tunnel would be worthwhile.
