OVERVIEW

The course aims to provide students with the necessary knowledge for the proper use of the basics of technical thermodynamics and heat transfer in the context of energy conversion systems.

AIMS AND CONTENT

LEARNING OUTCOMES

Demonstrate understanding of the nature and operating principles of systems involving energy flows.

Basic thermodynamic and fluid dynamics(gas – liquid – two phases) problems solution.

First law analysis and performance prediction of idealized forms of thermodynamic systems.

Describe and assess benefits of improvements to thermodynamic systems. Comparing different solutions.

Basic functional design of thermo-systems.

AIMS AND LEARNING OUTCOMES

Operational skills

At the end of the course the student will have understood the fundamental principles of thermodynamics and heat tranfer.

He will be able to apply these principles to the resolution of elementary problems of thermodynamics of fluids (gases, liquids, two-phase), and heat tranfer.

He will be able to carry out "first principle" analysis of energy conversion plants, direct and inverse: choice of the cycle, overall sizing (mass flow rate), functional sizing (heat balances).

He will be able to make comparisons between different possible solutions and to evaluate measures for the improvement of the performance of said plants.

PREREQUISITES

Basic notions of mathematics and physics

TEACHING METHODS

Lectures and final exam (via Teams)

due to the covid emergency, the lessons of the first semester 2020/2021 will be held online

SYLLABUS/CONTENT

This course provides an introduction to the essential theoretical basis of engineering thermodynamics and its application to a range of problems of relevance to practical engineering:   thermodynamic properties of working fluids including enthalpy and entropy; First Law of Thermodynamics applied to common engineering situations; Second Law of Thermodynamics applied to heat engines and refrigeration systems; common practical heat engine and refrigeration cycles. The course aims to equip students with basic tools and methodologies for carrying out thermodynamic analyses of engineering systems.

The course also provides elements of heat transfer, in particular heat conduction.

EXAM DESCRIPTION

There are two types of assessments 1. [only after Covid emergency] The general written exam at the end of the course (only in the academic year and reserved for those registered in that year, usually in January, session dedicated to this test), valid until the call of February, in the sense that the score must be accepted by e-mail at the latest by 10 March (ask for receipt of possible acceptance by e-mail) 2. The standard oral tests associated with the five sessions of January-February - June-July and September. The dates are available online (within the month of October). Specific details on the various tests are available on aulaweb

ASSESSMENT METHODS

The first question,a techical one, aims, in accordance with the training objectives (detail), to ascertain the ability of the student to solve elementary problems of thermodynamics (usually the analysis of a couple of transformations, part of a more complex cycle, direct or inverse). The test continues by verifying the ability and understanding of the student to manage mass and energy balances and generally to master all the elements of the first and the second principles provided during the course. The assessment also aims to verify the level of maturity achieved by the student in correctly assessing different solutions and in proposing variants and measures suitable for improving the performance of the system in question (steam or gas engine or refrigerator).
