Training objectives
- The aim of the course is the study of the unsteady behavior and of the control of energy systems (steam power plants, gas turbines, cogeneration systems) and of fluid machines (pumps, compressors and internal combustion engines).
The course provides the physical-mathematical background and the methodologies for the analysis of the unsteady behavior and of off-design operating conditions for the above-mentioned machines, in order to evaluate the most proper control logics. Particular attention is paid to system modeling in unsteady conditions, by presenting examples of model implementation in Matlab® environment.
The course also provides a methodology for energy system health state diagnosis, with particular reference to gas turbines. Prerequisites
- Fundamentals of mathematics and physics.
Energy systems.
Turbomachines. Course programme
- • Mathematical models of unsteady flow in open systems (4 hours)
• Control of compressors and operation at off-design conditions (12 hours)
• Regulation of energy conversion systems (22 hours)
• Control of reciprocating engines (6 hours)
• Health state determination of energy conversion systems (4 hours) Didactic methods
- Lessons will be highly interactive, and supported by lecture notes and references to specialized books. A practical lesson will be also held in the Information Technology laboratory, to develop a model (in Matlab environment) which allows the simulation of turbomachines under unsteady conditions.
Learning assessment procedures
- The examination takes place in 2 separate sessions:
- written session (both theoretical questions and numerical applications), on all the topics tackled in the class or on the basic concepts, with the aim to evaluate how deeply the student has studied the subject and how he is able to understand the basic topics analyzed;
- oral session, where the ability of linking different subjects is evaluated.
To pass the exam, a candidate has to exhibit basic knowledge on all course subjects; the mark (in the range 18-30) depends on the understanding and rigorousness about course topics. Reference texts
