This course focuses in the thermal design and optimization of energy systems and components with the twofold objective to improve efficiency and reduce cost of products. At the end of the course, the student will be able to analyse thermal systems and components by using advanced engineering thermodynamic methods and tools. He will be able to assess the energy performance of systems as well as to perform simple economic analysis and investment evaluation. Students will be able to identify the process of cost formation of products in a thermal system as well as to locate the source and nature of losses throughout a generic conversion process. Finally, dealing with thermal design of components, students will be able to optimize shapes and geometry by applying advanced thermodynamic methods. The course is composed by lessons, where the theoretical aspects are analysed and various applications to relevant systems are presented as well. A relevant part of the course is devoted to project team working using commercial software for the analysis of thermal systems and components.

At the end of this course, students are expected to know the techniques for design, analysis and optimization of thermal systems and their components from the energy and economic point of view: thermoeconomic analysis, estimation of cost of componnets and plants, fundamental of financial mathematics and discounted cash flow analysis, single and multi-objective optimization, design improvement, thermal diagnosis, entropy generation minimization.
