Learning Outcomes

• Students should gain a general familiarity with the concepts of pressure gain combustion, how this is distinct from traditional combustion devices, the different devices for achieving PGC, and especially the operation of the Rotating Detonation Combustor (RDC) • With regards to the RDC, students should have familiarity with the basic principles and operation of the combustor and some of the challenges and research focus ahead. This includes the experimental techniques for measuring and characterizing the performance. • From a theoretical perspective, students should have a fundamental understanding of the differences between deflagration and detonation combustion. This includes a basic understanding of: o the propagation of deflagration flames o the compressible gas dynamics of shock waves, and their impact on pre-heating and pressurizing the reactants o the simplified structure of a detonation wave o the key concepts of DDT and cellular structure, and how these concepts may be unique in the RDC. • Students should also get exposure to conducting literature reviews. This includes learning how to search for and distill out the relevant components of published works and then properly communicate the literature in the context of the current focus. • Students should also learn how to prepare, conduct, and analyze an experimental campaign. This includes organizing data into relevant and concise thoughts, and then being able to communicate these ideas, both in writing and verbally. • Students should be exposed to the process of working collaboratively and in a team. This includes constructively learning from and building off of each member’s individual skills.

Content

• Fundamentals of deflagration combustion, including key concepts of laminar and turbulent burning velocities and flame propagation mechanisms • Fundamentals of detonation combustion, including key concepts of Rankin-Hugoniot relations, detonation theory, structure, phenomena, and deflagration-to-detonation transition (DDT) • Fundamentals of compressible gas dynamics, including key concepts of normal shock relations, supersonic flows, nozzles, and shock wave reflections. • Thermodynamics of heat release processes, and differences between constant pressure and pressure gain thermodynamic cycles • Applications and pressure gain combustion devices • Focus on rotating detonation combustion, including key concepts of canonical operation, phenomena, and design • Experimental methods in PGC: measurements of combustion wave speed, pressures, temperatures, thrust, and performance • Future research challenges in PGC and open questions

Workload and Credit Points

Pressure gain combustion (IV):

Workload description	Multiplier	Hours	Total
Attendance	15.0	4.0h	60.0h
Pre/post processing	15.0	8.0h	120.0h
			180.0h(~6 LP)

The Workload of the module sums up to 180.0 Hours. Therefore the module contains 6 Credits.

Description of Teaching and Learning Methods

The fundamental and theoretical aspects of the course will be covered in twice-weekly integrated lectures. These lectures will present the theoretical concepts and will incorporate exercises (in groups and/or under-supervision) to demonstrate the key concepts. During the semester, students will be obligated to complete 3-5 homework assignments in groups. An experimental measurement campaign will provide a dataset, from which the students will submit a project (in groups).

Requirements for participation and examination

Desirable prerequisites for participation in the courses:

Fundamental knowledge of thermodynamics and heat, momentum, and mass transport, as well as some elements of the basics of combustion is desirable.

Mandatory requirements for the module test application:

This module has no requirements.
