Students are expected to have completed

- Calculus I
- Calculus II
- Physics I

Competences and skills that will be acquired and learning results. Further information on this link

The aim of this course is to understand the thermodynamic basic processes that determine the performance of elementary engineering devices (valves, turbines, compressors, pumps, heat exchangers) and the basic principles related to heat transfer, present in any field of engineering (electronics, electrical and thermomechanical).
A the end of the course the student must be able to:
- Understand thermodynamic properties, diagrams and processes.
- Identify the basic elements of a thermodynamic system, their function and working conditions such as temperature and pressure.
- Apply the basic equations of the different components.
- Analyze the operation of a system that integrates those basic devices.
- Understand the different mechanisms involved in heat transfer.
- Apply basic laws of heat transfer.
As for the different competences acquired through the lectures, it is worth to distinguish between specific and general skills.
With regard to specific competences the student must be able to:
- Estimate efficiencies of simple engineering devices or systems.
- Calculate working temperatures and pressures.
- Estimate thermal and mechanical power demand/production in different processes or devices.
The general skills trained during the course are:
- Problem solving methodology.
- The identification of the relevant thermal information that characterize industrial installations.
- Applying thermodynamics and heat transfer principles to solve problems.
- Group work abilities (Overall collaborative work, and presentation)
After completing the course, the student should have:
- A critical attitude towards identifying and evaluating the operation of basic equipment of an installation.
- A collaborative attitude that will allow obtaining information and knowledge from other agents to perform complex tasks.

Description of contents: programme

This is a basic course of thermodynamics and an introduction to heat transfer.
The program is divided into a thermodynamic section, a heat transfer section and a last section oriented to apply the acquired knowledge and student work.
Section I: First and second laws of thermodynamics. Application to turbines, valves, compressors, pumps and heat exchangers. Thermal efficiency. Power cycles and refrigeration cycles.
Section II: Introduction to heat transfer. Heat transfer principles: Fourier's law, Newton's law of cooling, Stephan-Boltzmann law. One-dimensional, steady-state conduction. Heat transfer from extended surfaces: fins design and performance. Transient conduction.
Section III: Applications and student work.

Learning activities and methodology

The learning methodology includes:
(1) Lectures covering the main topics described within the course outline. To facilitate the sessions, the students will have available the lecture's notes as well as reference books to complete their learning.
(2) Case study and problem solving lectures, where some issues are addressed from a practical point of view.
(3) Exercises solved by the student to self-assess their knowledge and acquire the necessary skills.
(4) Group projects.
