CODE 66384 ACADEMIC YEAR 2020/2021 CREDITS 6 cfu anno 2 INGEGNERIA MECCANICA - ENERGIA E AERONAUTICA 9270 (LM-33) - GENOVA SCIENTIFIC DISCIPLINARY SECTOR ING-IND/10 LANGUAGE Italian TEACHING LOCATION GENOVA SEMESTER 1° Semester TEACHING MATERIALS AULAWEB 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 course provides heat transfer foundations (conduction, convection, radiation) as well as advanced topics addressed to the field of mechanics/aeronautics discipline. 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. The course will be delivered in on-line modality for the I Semester of the 2020/2021 Accademic Year. SYLLABUS/CONTENT General conduction equation. Non dimensional heat conduction equation. Transient heat conduction in semi-infinite solids. Study and analysis of finned surfaces. Introduction to the finite volume method. Transient heat conduction in lumped systems and applications. Equations of forced convection. The concept of boundary layer for forced and natural convection. Forced convection in turbulent regime. Analysis of correlations for forced convection on plates. Forced convection in ducts.

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 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.
