Learning objectives
Knowledge and ability to understand: At the end of the trail
teaching the student should know the basics
of the computational thermo-fluid dynamics.
Skills:
The student will gain knowledge of applicative relatively
to the theme of the numerical analysis applied to heat transfer and, more generally, to
transport phenomena of energy mass and momentum involved in engineering processes.
Making judgments:
The student will have the tools to deal choices
design in the field of numerical modeling of the heat transfer devices.
Communication skills: The student will have the ability to present clearly the
procedure adopted in the numerical modeling of heat transfer devices.
Prerequisites
To follow the course with profit requires knowledge of the basic concepts
of Thermo Fluid Dynamics.
Course unit content
The course is structured into two parts: theory and practical lessons. The
theory lectures cover the following subjects: Equations of convection. Finite volume nanalysis. Finite element analysis. Turbulence and its models. The commercial codes for Computational Thermal Fluid Dynamics.
The exercise activity is an integral part of the course and is dedicated to
numerical exercises intended as a moment of verification and clarification
the theoretical knowledge acquired in the lectures. Part of the activities
Exercise is carried out in the computer lab and is dedicated
numerical analysis applied to
problems of heat exchange and fluid flow. In order to acquire
methodological knowledge and application, this part of the course makes use
practical exercises that use the programming Matlab, Comsol Multyiphysics and Ansys environment.

Teaching methods
The theoretical part of the course will be illustrated by means of lectures.
Part of the practical activity is carried out in the computer lab and it also
includes an activity pursued independently by the students, followed by
an elaboration and discussion of the results.
Assessment methods and criteria
The exam is based on a written/practical test, performed in the computer
lab, followed by an oral examination. The verification is so weighted: 50%
written test (correct resolution of a practical exercise), 50% oral exam
(correct and cmplete ansie to theoretical questions and speaking ability).
