Turbulent flows, with emphasis on engineering methods. Governing equations for momentum, energy, and species transfer. Turbulence: its production, dissipation, and scaling laws. Reynolds averaged equations for momentum, energy, and species transfer. Simple closure approaches for free and bounded turbulent shear flows. Applications to jets, pipe and channel flows, boundary layers, buoyant plumes and thermals, and Taylor dispersion, etc., including heat and species transport as well as flow fields. Introduction to more complex closure schemes, including the k-epsilon, and statistical methods in turbulence.
Course Outline (tentative and not exactly sorted)
- Review of flow and transport equations, with particular emphasis on the energy equation and the role of viscous dissipation.
- Instability and transition.
- Fundamental concepts in turbulence; approaches to closure and turbulence modeling.
- Jets, wakes, etc. modeled via simple closure schemes. Scalar transport in free flows (temperature, concentration).
- Buoyant plumes, transient thermals, etc.
- Turbulent flow over walls: general near-wall scaling laws; flows in pipes, channels, etc.
- Boundary layers.
- Transient dispersion in laminar and turbulent shear flows (Taylor dispersion).
- Turbulence models and their application.
- Additional topics (if time).
Each student has to do a project specific title agreed with the instructor in advance. Please talk me individually four weeks after beginning of the term in order to finalize it. The Project deadline is the last week of the current term. Take it Serious.
