K-ε Model

The k-ε (k-epsilon) model is a mathematical approach used in fluid dynamics to simulate turbulent flows, like air around an airplane or water in a pipe. It predicts how small, chaotic swirls (turbulence) behave by focusing on two key quantities: the turbulent kinetic energy (k), which measures the intensity of turbulence, and the epsilon (ε), which indicates how quickly this turbulence dissipates. By solving related equations, engineers can accurately model complex flows, helping design safer aircraft, efficient engines, and better environmental management systems.
