Wind blowing snow is a multiphase flow weather phenomenon that dispersed snow particles are carried by air flow and run near the ground, and is a more complex special fluid with great harm to the running of vehicles.
Currently, snow barriers are used to block the hazards of wind and snow blowing. When the snow blows and passes through the snow blocking fence, part of the snow blowing and blowing is blocked by the snow blocking fence, wind energy is lost, vortex is formed in front of the snow blocking fence, the wind speed of the snow blowing and blowing is rapidly reduced, the energy of the air flow for driving snow particles is weakened, and a large amount of snow blowing and blowing particles are deposited in front of and behind the snow blocking fence to form snow.
The snow barrier with different air permeability has great difference on the influence range and degree of wind speed, the lower the air permeability is, the better the blocking effect is, the greater the wind speed weakening degree is, but the faster the wind speed is recovered at the same time, so that the influence range is smaller.
