[0045] Example Take the wind erosion and wind accumulation effect research of photovoltaic power generation panels as an example:
[0046] (1) Model making in the wind tunnel: According to the actual survey size of the photovoltaic panels in the field and the conditions of the wind tunnel test section, the geometric scale ratio of the photovoltaic power generation panel model is designed and manufactured by 1:30, so as to meet the requirements of the cross-sectional area of the photovoltaic model in the wind tunnel. The blockage ratio in the wind tunnel is less than 5%, which is in line with the geometric similarity principle. The photovoltaic power generation panel model is at θ=55° to the horizontal plane. The vertical distance between the outer edge of the photovoltaic panel and the ground is 18.4 cm, and the vertical distance between the inner edge and the ground is 11 cm. The thickness of the sand covering at the bottom of the panel is 10 cm.
