Lecture
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.
