Gas Dynamics ESA 341 Chapter 0 Dr Kamarul Arifin B. Ahmad PPK Aeroangkasa

The Course Outcomes At the successful completion of this course the student should:  Understand the definition and fundamental aspects of compressible flow  Understand the definitions and types of shock and expansion waves: oblique-shock waves, shock-expansion interaction, and unsteady expansion waves.  Be able to do simple calculations related to applications of compressible flow on variations in geometry  Understand the concept of generalization of one-dimensional and two- dimensional subsonic and supersonic flows Aims To provide and introductory to the theories of compressible flows as part of the curriculum requirement and as a fundamental background to aerospace propulsion courses
