Training objectives
- The aim of the course is the study of thermodynamic cycle of turbomachinery at design and off design points.
The behavior of turbomachinery of different configurations and the trend of performance will be studied.
The course also deals with the faults in turbomachinery and their root causes.
Diagnostics will be described in order to have an early detection of faults. Prerequisites
- Fundamentals of mathematics and physics.
Energy systems.
Fluid machines. Course programme
- The course is composed of 60 hours of both classroom lectures and tutorials.
The main topics developed during the course are:
• Different configurations of turbomachinery.
• Study of thermodynamic cycle at design point.
• Study of the influence of main cycle parameters.
• Study of cycle at off design conditions.
• Influence of both operative and design parameters.
• Trend analysis and diagnostics.
• Matrices of influence.
• Their structure and calculations.
• Use of matrices of influence for detecting the faults.
• Importance of reference parameters.
• FMECA
• Classical Diagnostics and use of Artificial Intelligence Didactic methods
- Lessons will be highly interactive and supported by lecture notes and references to specialized books. Moreover, examples of the most outstanding cases and practical applications will be provided.
Learning assessment procedures
- The written exam, eventually followed by an integrative oral examination, aims at checking the level of achievement of the previously mentioned didactic goals.
To pass the exam, a candidate has to exhibit basic knowledge on all course subjects; the mark (in the range from 18 to 30) depends on the understanding and rigorousness about course topics. Reference texts
