## Properties

• Semester hours: 3.0
• Credits: 5.0
• Type: VU Lecture and Exercise

## Learning outcomes

After successful completion of the course, students are able to:

• Understand the fundamental notions of gas dynamics and aerodynamics, integrating specific knowledge with that of other related fields in engineering (for example thermodynamics and fluid mechanics);
• follow specific physico-mathematical reasoning that are required to understand and model gas/aerodynamics problems;
• understand and solve simple problems encountered in aerospace/industrial/chemical applications;
• develop learning skills necessary to undertake further study with a high degree of autonomy;

## Subject of course

Gas dynamics: Introductory concepts, fundamental definitions and equations, speed of sound, Mach number, thermodynamics; Steady isoentropic flow, choked flow, subsonic and supersonic nozzles; De-Laval nozzle, Hugoniot equations; Flow with friction, Fanno line; Flow with heat addition, Rayleigh line; Shock waves, conservation relations, normal and oblique shocks. Aerodynamics: external flows, aerodynamic forces and moments; skin friction, pressure drag and lift;  incompressible flow around an airfoil;  NACA airfoils; modern low-speed NASA airfoils; Finite wings; Linear theory for subsonic and supersonic compressible flow over an airfoil;  elements of hypersonic flow. All themes will be illustrated via examples and exercises.

## Teaching methods

The following methods will be used to support students in achieving the expected learning outcomes:

• Calculation of examples and case studies at the blackboard;
• Assignment of homeworks to be solved (within a certain deadline, typically 1 week) independently by the students; discussion of the corresponding solution strategies/results with the students
