turbulence closure

Turbulence closure refers to a set of mathematical methods used in fluid dynamics to model turbulent flows, which are complex and chaotic movements of fluids like air or water. Since turbulence features many unpredictable fluctuations, closure is needed to simplify and make sense of these equations. Essentially, it involves creating approximations or relationships that link the flow properties to permit calculations. Without closure, the equations are too complicated to solve, making it crucial for engineers and scientists to predict behaviors in various applications, from weather patterns to aircraft design.
