Turbulence: Drag Coefficient and Dissipation Rate

This lecture covers the concept of drag coefficient and dissipation rate in turbulent flows, emphasizing the influence of viscosity and control parameters. The instructor discusses the existence of a velocity-independent drag coefficient and the behavior of dissipation rates in different scenarios, such as in a spherical cylinder. Additionally, the lecture delves into the laws governing dissipation and the implications for force on objects in turbulent flows. The Kolmogorov K41 theory, Navier-Stokes equations, and energy transport are also introduced, providing a comprehensive overview of turbulence analysis.
