With. What is tailwind?

The so-called “windward” exit refers to the direction from which the wind blows. If the wind blows from the north, then the windward point is north. The direction away from the wind is the upwind exit.

What we call leeward is the place where the wind blows. If the wind blows from the south, the north direction is the leeward direction. The direction facing the wind is the downdraft.

Detailed Information

Many fishing friends choose to fish in the lower spout, because it can increase the amount of dissolved oxygen in the water. after being blown by the wind. In windy summer, the amount of dissolved oxygen in the leeward outlet is greater than that in the upwind outlet. Fish tend to swim towards the leeward exit where the dissolved oxygen content is higher due to the warming characteristics. and oxygenation. Second, the food brought by the wind will be blownin the water by the wind and will float in the wind, forming a natural fish nest.

There is no lack of oxygen in the body of water in the fresh autumn air. At this time, the temperature of the upper air outlet is not blown by cold air. Compared to the lower air outlet. the temperature is higher and the water surface is calmer, so there are more fish at that time.

How to choose a site for wind energy production? Does anyone have any professional information~~~~

Blower type and suction type.

Engine

An engine is a machine capable of converting other forms of energy into mechanical energy, notably internal combustion engines (gasoline engines

, etc.), External combustion engines (Stirling engines, steam engines, etc.), electric motors, etc. For example, internal combustion engines typically convert chemical energy into energy.mechanical engineering. The engine applies to both the power generation device and the whole machine including the power device (such as gasoline engine, aviation engine). The engine originated in England, so the concept of engine also comes from English. Its original meaning refers to the “mechanical device that generates energy”.

Fan

Fan refers to a device used to generate wind and cool down during hot days. An electric fan is a device that uses electricity to generate airflow. The fan inside is powered and rotates by natural wind to achieve a cooling effect.

① Determine the local main wind direction and the wind turbine should be installed upwind of the main wind direction.

② At the same time, it is necessary that there are as few other houses or buildings as possible upwindof the wind turbine. The presence of obstacles such as trees.

③ Try to avoid the influence of wind turbulence. Turbulence is caused by sudden changes in wind speed and direction caused by wind passing over uneven ground or obstacles. Turbulence causes the wind turbine's power output to decrease and makes the wind turbine vibrate, causing noise and affecting its service life. In order to avoid the influence of turbulence, the wind turbine should be installed in a relatively open and unobstructed place, at a certain distance from the house.

④ The vertical shear of the wind speed in the height range of the wind turbine rotor should be small. Vertical wind speed shear refers to the different wind speeds at each level in the height direction. Due to the terrain and roughness of the ground, vertical shear causes wind turbine blades to be unevenly distributed. The force can easilymay damage the wind wheel. In order to avoid the impact of vertical shear of wind speed on the wind rotor, the appropriate installation height of the wind turbine should be selected. In places where there are many obstacles and the wind turbine needs to be installed close to the house, it should be considered to increase the installation height of the wind turbine.
