Gennaro Coppola
Introduction to the theory of turbulence.
Navier Stokes equations and averages. Reynolds equations, Reynolds tensor and closure problems. Further definitions: turbulent kinetic energy, production and dissipation; induced balance equations.
Turbulence modeling
Kolmogorov theory: basic results. RANS models: turbulent viscosity hypotesis. Algebraic models and mixing length. Kinetic energy based models: k-epsilon and k-omega.
NS integration metodologies
Survey of various discretization methods. Finite volume method and variables layout. Pressure equation and pressure correction methods. Implicit schemes: SIMPLE algorithm and extensions.
Class Notes Almerinda Di Benedetto
Turbulent reactive flows
Mass and Energy balance equations coupled to the Navier-Stokes equations in turbulent conditions, compressible flows. Favre Average. Equations closure problems.
Subscale modeling
Subscale modeling for the RANS approach, advantages and disadvantages, range of applications. Diagram of turbulent combustion regimes.
Case Study with ANSYS Fluent
Development of models with the commercial software ANSYS-Fluent (www.fluent.com). Training in the room with the tutor.
Lectures will be given in Italian, if the course will be attended by non-Italian students lectures will be given in English.
