Affordable and clean energy

Academic Year 2021/2022

Learning outcomes

At the end of the course the student is able to model and solve problems on the following topics: energy analysis of thermodynamic systems, newtonian fluid flow within ducts under laminar and turbulent regimes, heat conduction in plane and cylindrical geometries, including internal heat generation, convection heat transfer, radiation heat transfer, in plane and cylindrical geometries.

Course contents

Notice: the English version of the course is sketchy because it will be held in Italian anyway, so the following is only aimed at giving a potential foreign student a general impression of the course prior to choosing whether to enlist for the Italian degree in 'Ingegneria Biomedica'. For further details, please e-mail the instructor.

Introduction: basics and definitions. The first law of thermodynamics for closed systems. Thermodynamic properties of pure substances. Control volumes and the first law. Second law of thermodynamics for closed systems. Entropy. Steam power cycles and vapor compression refrigeration cycles. Gas turbine cycles. Fluid mechanics. Momentum and energy conservation equations. Basics of heat transfer. Unsteady heat transfer. Conduction heat transfer. Convection heat transfer. Radiation heat transfer. Biothermal equation.

Teaching methods

Numerical examples where theoretical principles are applied; use of thermodynamic tables and charts to solve problems.

Assessment methods

As long as tests cannot be sat in classroom, the assesment is through a short report and the solution of a numerical problem which are assigned on a personal basis by the examinator, for marks between 18 and 22. For higher marks, an oral exam (via MS Teams) is also mandatory. Please contact the examinator for further details

Teaching tools

Lectures and exercises in the classroom.
