Learning objectives

Knowledge and ability to understand: At the end of the course the student should know the basics of the computational fluid dynamics and heat transfer.
Skills:
The student will gain applicative knowledge relatively to the topic 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 design choices 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 difference analysis; Finite volume analysis; Finite element analysis; Errors and accuracy of numerical models; 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 practical
problems of heat transfer and fluid flow typical of engineering applications. In order to acquire methodological knowledge and application, this part of the course is based on practical exercises developed within Matlab and Comsol Multyiphysics environment.

Teaching methods

The theoretical part of the course will be illustrated by means of lectures and seminars on specific topics.
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.
If conditions are favorable, seminars, held by R&D managers of local companies, are additionally proposed to the students with the aim of reporting concrete experiences of real case studies in the field of the heat transfer apparatuses CFD modeling.

Assessment methods and criteria

At the end of the lessons students are offered a series of themes/project works related to applicative problems to be addressed by students in the Comsol Multiphysics / Matlab environment. Verification of learning is based on the discussion of the work chosen and carried out by the student. The discussion of the project work is completed by an oral test in which the correct and complete response to theoretical questions and speaking ability are evaluated.
The vote is so weighted: 70% evaluation and discussion of project work and 30% oral test. The Laude is added in case of excellent score in each item (written test and oral exam) and in case of particular communicative and speaking ability with reference to the specific field.
