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 On successful completion of this module, students should demonstrate: Knowledge and understanding of the heat transfer equations, including their application to complex problems, also in case of on combined heat transfer mechanisms; Ability to propose solutions to limit/enhance heat transfer in complex systems; Ability to select the most suitable numerical or analytical method for the solution of the heat transfer equations (dimensionless formulation, numerical methods). PREREQUISITES Bachelor level knowledge in heat transfer and thermodynamics is mandatory. TEACHING METHODS Lectures Students who have valid certification of physical or learning disabilities on file with the University and who wish to discuss possible accommodations or other circumstances regarding lectures, coursework and exams, should speak both with the instructor and with Professor Federico Scarpa (federico.scarpa@unige.it), the Polytechnic School's disability liaison.

The aim of the examination is to assess the student knowledge and the skill in reasoning and subject presentation. Students with learning disorders ("Disturbi Specifici di Apprendimento", DSA) will be allowed to use specific modalities and supports that will be determined on a case-by-case basis in agreement with the delegate of the Engineering courses in the Committee for the Inclusion of Students with Disabilities.
