Turbulence

Definition

Turbulence refers to the chaotic and irregular motion of fluid particles, often characterized by swirling eddies and rapid changes in velocity. This phenomenon is crucial in simulating realistic natural environments, especially in particle systems, where it adds complexity and dynamism to the behavior of particles. Understanding turbulence helps artists and developers create more immersive and lifelike animations or simulations, enhancing visual realism in digital content.
