The most advantageous flat shape against the wind is the circle.
1. Advantages of the circle
The reason why the circular shape is beneficial for wind resistance is that it can disperse the force of the wind over a larger area, reduce the weight of the building to reduce the damage caused by the wind to buildings. The round shape can also reduce the impact and vibration of the building, thereby improving the stability and earthquake resistance of the building. When designing buildings, choosing a circular plan shape can effectively improve the wind resistance of the building.
2. The emergence of wind
Solar radiation is the source of energy generated by the wind. Due to the uneven heating of the Earth's surface, the temperature is different in different areas, resulting in different temperatures. in a temperature difference. This temperature differencecauses air to move, creating wind. The Earth's rotation will deflect the direction of airflow, forming winds in different directions.
3. Principle
The circular planar shape can evenly disperse the wind force and reduce the wind area, thereby reducing the impact of the wind on the building. In non-seismic zones, wind load is the main horizontal force on building structures. The shape of the building directly affects wind direction and speed, thereby changing the magnitude of wind pressure. Experiments have shown that buildings with a circular plan can reduce wind pressure by almost 40% compared to square or rectangular buildings.
4. Application
Wind is an extremely valuable natural resource and has many applications in many areas. Wind energy is a clean and renewable energy. Human beings can converseturning wind energy into electrical energy by creating wind power plants and other means to provide continuous energy for production and life. It can help plants spread seeds and pollen and promote plant reproduction and distribution.
Practical application of wind in life
1. Sailing aids navigation
Sailing is a technology that uses wind energy to propel a ship forward. Through the interaction between a sailboat and wind energy, navigation and maneuvering of the ship is achieved. Sailing was used to drive ships in ancient times. With the development of science and technology, sailing technology has also been improved and perfected. Sailing technology is a technology with broad application prospects, bringing more convenience and advantage.benefits to the shipping industry.
2. Wind water lifting
Wind water lifting refers to a technology that uses wind-generated energy to pump groundwater or water sources to the ground or in height. Water pumping by wind power is widely used in many places, including agriculture, irrigation, water supply and rural drinking water security. Wind water lifting system consists of wind turbines, electric motors or mechanical transmission mechanisms, water pumps, tanks, etc.
