054233 - COMBUSTION PROCESSES IN THERMOCHEMICAL PROPULSION
The course provides the students with a broad introduction to the principles of combustion, which form the background to all combustion phenomena, as well as applications to the different air-breathing and rocket propulsion systems. It involves a multidisciplinary view of combustion processes and aims to advance the capacity to quantify parameters, constraints, possible improvements of combustion processes in aeronautical and space propulsion systems.
The layout of the course is shown in the index.
Part I focuses on fundamentals of combustion, formulated from general principles of chemistry, physics, gasdynamics and thermodynamics, pointing out the essential feature of all combustion phenomena based on the interplay of multidisciplinary processes.
Part II deals with combustion processes in thermochemical propulsion systems.
Part III presents a short summary of advanced experimental and numerical techniques for the investigation of combustion processes.
Advancement of the team spirit in laboratory experimental activities.

The essential scientific background to understand combustion phenomena involves the knowledge of mathematics (understanding of ordinary and partial differential equations), thermodynamics, elementary gas dynamics, chemistry, in addition to competence in topics such as heat engine cycle analysis and the concept of turbulence.
Modalità di valutazione
Teaching activity: lectures, exercises, numerical and experimental laboratory activities.
Working Group: students are required to develop a project working in small groups.
Oral test at the end of the course, including a discussion of the project.
The evaluation is based on the shared ‘Dublin’ descriptors for the Master’s, which include:
- the ability to demonstrate knowledge and understanding that is founded upon and extends and/or enhances that typically associated with Bachelor’s level;
- the ability to apply knowledge and understanding, and problem solving abilities in new or unfamiliar environments within multidisciplinary contexts related to the field of combustion;
- the ability to integrate knowledge and handle complexity, and formulate judgements, reflecting on social and ethical responsibilities linked to the application of knowledge and judgements;
- the ability to communicate the knowledge and the conclusions of the project clearly and unambiguously.
Assessment of the preparation is based both on the report of a project developed by the working group, and on the oral individual exam, aimed to verify the knowledge of the topics dealt with in the lessons.
During the exam the students have to demonstrate:
- the knowledge of physics, chemistry, gasdynamics involved in combustion processes;
- the working knowledge of combustion processes in thermochemical propulsion systems;
- the good presentation of the project results, and their critical judgement, described in the technical report.
