Turbulent Flows - I

This course covers the comprehensive understanding of turbulent flows, their applications in engineering and nature, and the mathematical equations used to predict their behavior. For instance, learners will explore how turbulent flows are utilized in jet flows, mixing flows, and flow over an aerofoil section. They will also examine real-world examples of turbulent flows such as river flows and wind flow over the earth's surface. The course further delves into the derivation of the Reynolds Average Navier Stokes (RANS) equations, which are crucial for turbulent flows. Learners will understand the decomposition of velocities into mean and fluctuating components, leading to additional stresses in the governing equations. The course concludes with a discussion on the closure problem in turbulence modeling and the concept of turbulence intensity.
