Kolmogorov scales represent the smallest scales in turbulent flow where viscous forces dominate, and kinetic energy is dissipated into heat. They are critical in understanding the energy cascade process in turbulence, marking the transition from inertial to viscous subranges.

Viscous forces are internal frictional forces within a fluid that resist the relative motion between different layers of the fluid. These forces are crucial in determining the flow behavior of fluids and are characterized by the fluid's viscosity, which quantifies its resistance to deformation or flow.

Viscous Forces

Kinetic energy is the energy possessed by an object due to its motion, and it is directly proportional to the mass of the object and the square of its velocity. This form of energy is a fundamental concept in physics, playing a crucial role in understanding the dynamics of systems and the conservation of energy principle.

Energy cascade process

Turbulence is the chaotic, unpredictable flow of fluids characterized by vortices, eddies, and rapid changes in pressure and velocity. It plays a critical role in various natural and industrial processes, affecting weather patterns, aircraft performance, and energy efficiency in systems like pipelines and turbines.
