Objectives

The course aims to initiate the student to the implementation and subsequent use of algorithms for the simulation and performance prediction of conventional and innovative energy conversion systems. The educational objectives and the expected results are the following:
1. To acquire knowledge in computer codes for the process simulation and energy systems performance predictions.
2. To provide the ability to develop mathematical models from real industrial processes and energy systems of varying complexity, to set energy and mass balances, to manage the design and operative parameters, to introduce physical and operational constraints, to optimize system configurations, to perform parametric analyzes, etc.
3. To acquire the ability to rightly interpret the results, to recognize and assess the correctness and physical consistency of the obtained data, to deal with the simulation codes in order to improve functionality and adherence to the real system, etc.
4. To acquire the ability to represent, outline, describe, summarize and comment the developed simulation models and the results of their application systems.
5. To acquire skills in the application of techniques and simulation methods that enable to independently develop conceptual simulation models of processes and systems.

Prerequisites

- knowledge of the basics of thermodynamics of non-reactive and reactive fluids, fluid mechanics and machines
- knowledge of power plants technologies learned during Bachelor Degree courses
- Basic knowledge of MATLAB software

Teaching Methods

The course has a total duration of 30 hours (corresponding to 3 CFU), 4 hours of lectures, 10 hours of practical exercise and 16 hours of laboratory activities. The course will be done in blended mode, with classroom and online lectures, according to the decisions of the University management.
During the lectures, the use of multimedia computer presentations will be privileged. The practical exercises are solved in the classroom by the teacher and concern the design and the performance evaluation of different types of energy systems. The laboratory activity mainly consists of the implementation of classroom exercises in the MATLAB environment. Both during the exercises and during the lab activities, computer supports will be used (virtual whiteboard, PCs).

Verification of learning

The final test consists of an oral exam based on the presentation and discussion of a report concerning the sizing, performance evaluation, and techno-economic optimization of different types of energy systems.
The following criteria are applied for the evaluation of the oral examination: a) suitability of the assumptions and correctness of the resolution process, b) Effectiveness of graphics and discussion of results; c) language skills and effectiveness of the presentation.
Course attendance is mandatory. The exam can be sustained only by the students who have attended an adequate number of lessons.
