The main objective of the 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.
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
Practical sessions and frontal lectures
The course will be delivered in on-line modality for the I Semester of the 2020/2021 Accademic Year.
