Leerdoelen At the end of the course, the student is able to:
1.
Explain the basic underlying principles in ideal compressible flows and the importance of the relevant dimensionless groups.
2.
Use the different mathematical tools available to describe and the different types of compressible flows encountered in engineering, namely: flow with area change (including normal shock waves), flow with friction (Fanno flow), isothermal flow (long pipes) and flow with heat transfer (Rayleigh flow).
3.
Select, based on the evaluation of the model, the appropriate simulation environment in order to analyze these
processes.
4.
Compare the different models and discuss their range of applicability/limitations based on the assumptions made.
5.
Visualize the flow behavior of these systems in terms of Mach number, pressure and temperature, and debate over the influence of these parameters on the mechanical design of a system.
6.
Use the models to predict the behavior of the process based on the inlet/gas properties and formulate strategies in order to improve their performance if the operating conditions change.
Omschrijving The course aims at giving an introduction to the analysis of compressible flows of ideal gases in engineering, and it is intended to provide a base for future, more advanced studies of these systems. This course integrates then the knowledge the students gained in their previous years in mathematics, thermodynamics and chemistry courses. This is then applied into a series of examples and reports, including also the use of computational fluid dynamics tools.

Firstly, the importance dimensionless groups and the speed of sound in ideal gases are thoroughly discussed. Then the basic conservation equations are applied for the different flow patterns usually found in industry, namely: isentropic, heat transfer, friction and isothermal. Among these, a basic introduction to normal shock waves is presented in order to understand some phenomena taking place in certain chemical operations (e.g. flow in turbines, pressure safety valves). Starting with fundamental knowledge of thermodynamics and fluid mechanics, the course proceeds with the discussion of solving techniques and examples encountered in the industry.

During the course the study and modelling of different processes will be carried out in a series of simple cases, finalizing with the development and application of a numerical models using the software provided by
the university (i.e. COMSOL).

The students will be evaluated by the assessment of a number of reports, in which they have to perform a deep literature study and analysis (step by step) of the solution process and modelling, ending with the summary of the phenomena analyzed and conclusions about possible applications/problems in industry. This will be complemented with a written exam.

Entreevoorwaarden The course assumes prior knowledge acquired from bachelor (chemical) engineering curricula, including (but not limited to) transport phenomena, calculus, thermodynamics and fluid mechanics. The students should also have at least a basic knowledge of algebra, differential equations and numerical methods in order to solve the problems. Even though it is not mandatory, it is advisable to have a basic knowledge in computer modelling.
Opmerkingen The minimum grade has to be 5.5 in every of the assessment procedures used on the course. Students can take the exam without having approved the reports but these must be improved. The students have one opportunity to improve the grade from the exam.
