What is the border layer in physics?
The border layer occurs when the liquid flows around a solid surface. It is usually defined as an area of fluid whose speed is less than 99% of the unmo -leaked fluid flow. In other words, it is a movable fluid zone that is slowed by more than 1 percent by a stationary surface. The border layer was defined to better understand the fluid mechanics by distributing the flow into two areas that show different behavior. The regions inside and outside the marginal layer also generate friction in different ways.
The early problem in aerodynamics research was the solution of complex Navier-Stoke equations that are expected to control the flow of fluid. There are many cases where the solution of Navier-Stokes equations are unknown. However, it was found that the flow of fluids showed two general behavior: laminar and turbulent. Laminary flow is a smooth and predictable flow, like a flow of balls falling over honey. The turbulent flow is random and violent, which is based on a fire hose.
border layer OIt deals with these two fluid flow zones. Inside the boundary layer, the flow is primarily laminar. In this area, the flow behavior is dominated by viscous tension. The viscous voltage is directly proportional to the speed of the passing object; Highly viscous liquid, such as honey, stores objects of high friction that moves quickly. The laminar flow is characterized by fluid flowing in parallel lines without irregularities.
Outside the border layer, the flow of fluids is dominantly turbulent. The turbulent flow, whether in liquid or gas, shows similar behavior. Chaotic changes in the speed and direction of particles prevent precise predictions with current knowledge. The effect of friction in the turbulent flow also varies from laminar flow. Friction in general is no longer proportional to the speed of fluids in the turbulent region.
The reason why golf balls have holes in them are related to the border layer of air. At low speeds such as runningHEM, a perfectly spherical golf ball would not have a big problem with air friction. However, during a high-speed flight, spherical golf balls would have a larger marginal layer than a muted ball-that would mean that the laminar method would flow more air. In fact, this laminar flow would cause more air friction than a turbulent flow. Golf balls thick fly further than their spherical counterparts because they have a smaller marginal layer and do not experience so much air friction.
