OBIETTIVI FORMATIVI

The objective of the teaching is to provide the basic knowledge of fluid mechanics with a particular attention to mass transport processes. Examples of practical problems are formulated and solved during the lessons.

OBIETTIVI FORMATIVI (DETTAGLIO) E RISULTATI DI APPRENDIMENTO

The main objectives of the course are:
1. To provide the basic knowledge on fluid mechanics, as a starting point for the description of transport processes
2. to provide basic theoretical knowledge needed to better understand which are the most suitable models for the study of transport processes in different contexts

PREREQUISITI

Basic knowledge of Pysics, Caculus and Fluid Mechanics

MODALITA' DIDATTICHE

frontal lectures

PROGRAMMA/CONTENUTO

The course program can be mainly divided into two:
1. Fundamentals of fluid mechanics

In this part we will recall some basic principles of fluid mechanics and in particular: Kinematics. Dynamics of viscous fluids: Navier-Stokes. Inviscid Fluids. Vorticity dynamics

2. Turbulent flows

In this part we describe the transition process from the laminar to the turbulent regime, the decomposition of a turbulent flow in an ensemble averaged component and in a fluctuating component (Reynolds decomposition), the averaged equations (continuity equation and Reynolds equation), the kinetic energy of the averaged flow and of turbulence and their dynamics.

2. Transport processes

In this part we describe the fundamentals of molecular diffusion (Fick law), turbulent diffusion, the eddy vicosity and diffusivity, turbulence models, the log-law, the two-equation models, the oundation of dispersion (theory of Taylor and dispersion in ducts).
