### Descrizione dell'insegnamento

The course is focused on the study of the transport phenomena occurring in fluid/solid materials: mass, heat and momentum transfer. These phenomena greatly regulate and control all the processes (transformation, production, manufacture, etc.) involving materials in their whole life cycle. The course will illustrate the use of: balances (of mass, energy and momentum), both in microscopic and macroscopic scales and in laminar and turbulent flow; transport coefficients (friction, heat and mass) between different phases; empirical correlations for turbulent flow. Several case studies will be presented in the course, in order to illustrate the practical use of the mathematical equations introduced in the lessons.

Applying knowledge and understanding:

The course provides abilities in transport phenomena problem solving  applied in materials engineering field.

Making judgements:

The course gives the ability to integrate knowledge and handle complexity, and to solve transport phenomena problems occurring in fluid/solid materials: mass, heat and momentum transfer.

Communication

Students have to be able to communicate  their conclusions and rationale to specialist

, by using a technical language based on formulas and theorems,  and non-specialist audiences by using a narrative language based on elementary concepts.

Learning skills

Students are trained to develop  creative thinking,  critical spirit,  and autonomy , by using as a knowledge technique  examples and counter-examples. The theoretical approach of the course  is a good tool  to improve their ability of abstraction
