Wind tunnel test on damages of plastic film under the wind

2021-2-25  Wind angle has significant effect on the time of the plastic film damage. When the angle is 45°, the wind force acting on the plastic film reaches its maximum 2.29 N. At this moment, the plastic film is damaged with the edges blown off. When the thickness of the soil on the film is increased, the film becomes more resistant to the wind. The time variable K is calculated using the test data and the mathematical model of the film damage under the wind

Wind Tunnels an overview ScienceDirect Topics

The effect of additional damping in an aeroelastic wind tunnel model can, in some cases, be physically modeled by applying small strips of cellular or plastic tape between the different sections of the cladding of the model ( Kwok and Samali, 1995; Facioni et al., 1995; Kim

Plastic Tunnels for Early Vegetable Production UC Small

Many of the difficulties growers have experience using plastic tunnel technology have resulted from inadequate planning in dealing with wind conditions. Growers must be aware of the wind conditions in their area before deciding to use tunnels. Plastic tunnels are not designed to withstand high winds or whirlwinds (Figure 11).

Plastic Tunnels to Grow Vegetables

A plastic tunnel is easily made by draping plastic sheeting over a series of sturdy wire or plastic hoops to create an enclosed growing space. A plastic tunnel works much like a cold frame. The temperature inside a clear or opaque plastic tunnel can be heated by the sun 5, 10, or even 20 degrees F (2.8-12 degrees C) warmer than the outdoor temperature during the day.

Then a clear plastic cover is fashioned to lay over the tunnel supports creating a little greenhouse. The plastic is held down by bricks. The tunnel protects early spring plants and late fall plants from frost and wind damage. It keeps the air temperature high enough for the plants to grow and helps the soil temperature stay high.
