Turbulence is an erratic or agitated motion that can occur in liquids and gases when there is an interruption or impediment to flow. It can be caused by various factors, making it difficult to predict and control. Examples include obstacles in a river, weather fronts colliding, and domestic pipes.
Turbulence is a form of motion characterized by an erratic or agitated motion. Both liquids and gases can experience turbulence and a number of factors can contribute to the formation of turbulence. When a liquid or gas is moving smoothly and evenly, it is said to exhibit laminar flow, which is the opposite of turbulent flow. Many people interact with some variety of turmoil on a daily basis.
This phenomenon occurs when an interruption or impediment to flow is introduced. For example, a river may flow smoothly until it hits a boulder, at which point the water around the obstacle will become turbulent as it moves around or over it. In the air, turbulence can be caused by things like two weather fronts colliding or a storm forming. Air turbulence can also be caused by obstacles on the ground, ranging from mountains to buildings.
While people understand what causes turbulence, it can sometimes be difficult to figure out, because it’s erratic and can defy predictions. Rough and erratic motion usually involves motion at various speeds, and a number of factors can affect the motions of liquids and gases. This is why turbulence in an aircraft can be difficult to predict and why planes can be moved in different ways by turbulent air patches, depending on where they are.
Air is indeed quite turbulent, because it is constantly moving at different speeds and pressures across the Earth. Most of the time people can’t see this turbulence in action because the air is clear, but turbulent motion can occur when particles fill the air, showing their erratic motion, or when an object is thrown into the air. , in which case the object’s motion through space will reflect changing speeds and pressures in the air through which it travels.
Many people have domestic pipes that cause turbulent flow, in which case the water squirts out of the pipe instead of flowing smoothly. People can also observe this interesting property of fluid dynamics when they look at smoke rising from a fire. Classically, the smoke starts out straight, then rapidly begins to swirl and swirl as it rises. The heat from the fire can cause turbulence, affecting the air above the fire, and things like breezes can also affect the smoke’s movement.
