OVERVIEW

The  outcomes of the Heat Transfer course are:

-To provide an advanced knowledge of the main principles of heat transfer;

-To study heat transfer phenomena involved in applications and processes of interest for the mechanical engineering;

-To illustrate the principles of heat transfer design of processes and components.

AIMS AND CONTENT

LEARNING OUTCOMES

The main objectives of the course are: to provide students with an in-depth study of the heat transfer principles; to study heat exchange phenomena in components and processes of particular interest for mechanical engineering; to introduce the main methodologies used in the thermal design of components and systems.

AIMS AND LEARNING OUTCOMES

This course is aimed at providing the basic knowledges, from the theoretical (heat transfer laws and governig equations) and practical (problem solving) standpoints. Solution of practical problems based on combined heat transfer mechanisms, numerical methods (time discretization and finite volume method), thermo-economics and optimization will be proposed during the course.

On successful completion of this module students should demonstrate:

1 – Knowledge and understanding of the conduction and convection equations, including their application to complex systems;

2 – Ability to calculate heat exchange in different unfamiliar configurations  by choosing the most suitable numerical or analytical method;

4 – Ability to propose solutions to limit/enhance heat exchange in complex systems (e.g. heat exchangers, finned surfaces, etc.)

5 – Ability to interpret technical diagrams for the estimation of relevant parameters (e.g. fins, erf, etc.)

6 – Ability to illustrate the heat transfer equations and their fundamental hyphothesis

PREREQUISITES

Bachelor level knowledge in heat transfer and thermodynamics is mandatory.

TEACHING METHODS

Frontal theoretical lectures and practical exercises also computed based.

EXAMS

EXAM DESCRIPTION

Examination: oral (after passing a preliminary design or written test).

Examinations are scheduled according to the official calendar; in case of a negative evaluation (or with a score not accepted by the student) it can be repeated only once during the same session (winter o summer session) and no more than twice throughout the same academic year.

ASSESSMENT METHODS

After passing a preliminary design or written test, oral examination, based on a specific subject among those tackled during the taught course, with in addition a couple of small synthetic questions on other one/two subjects.

The aim of the examination is to assess the capability of solving specific thermal problems (including physical formulation and mathematical passages) and the skill in  discussing and arguing them.
