Abstract:

Based on Bernoulli′s equation and hypothesis of wind speed attenuation in isolated tree crown, models of drag and drag coefficient of isolated tree are deduced respectively. This model prediction agrees well with data of wind tunnel experiment.

Key words: Isolated tree, Drag, Drag coefficient, Bernoulli&prime, s equation
