An analysis of tree stand stability relative to Institute of Meteorology and Water Management (IMGW) classification of maximum wind velocities

چکیده
Analysing tree susceptibility to uprooting one has to compare external power acting on a tree with its resistance to uprooting (critical moment). The critical uprooting moment for a tree depends on both plant parameters and substratum. Results of an assessment of critical moments of studied pine and black alder tree stands are presented in this paper. Field studies consisted of uprooting trees with parallel measurements of critical moments. Results were compared with the moments of uprooting power of extreme winds. These moments were related to classification of maximum wind velocities proposed by the Institute of Meteorology and Water Management (IMGW).

Applying corona wind as a novel technique can lead to a great level of heat and mass transfer augmentation by using a very small amount of energy. The enhancement of forced flow evaporation rate by applying electric field (corona wind) has been experimentally evaluated in this study. Corona wind produced by a fine wire electrode charged with positive high DC voltage impinges on water surface an...
