Compressible Flow 4

Overview

Steady Compressible Flow: Euler’s equation. Speed of sound. Mach number. Mach cone. Stagnation & static conditions. Isentropic 1D flow equations. Mass flow relationship. Critical conditions. Use of flow
tables to analyse problems. Converging nozzles. Converging-diverging nozzles. External flows. Normal shock. Supersonic pitot tube. Oblique shock. Unsteady Compressible Flow: Acoustic waves, Finite Amplitude wave theory, mass moved by a wave, superposition, reflections at pipe ends, sudden area changes, branches and ports. Application to engine tuning.

Learning Objectives

Apply a comprehensive knowledge of mathematics, statistics, natural science and engineering principles to the solution of complex problems. Much of the knowledge will be at the forefront of the particular subject of study and informed by a critical awareness of new developments and the wider context of engineering.

Formulate and analyse complex problems to reach substantiated conclusions. This will involve evaluating available data using first principles of mathematics, statistics, natural science and engineering principles, and using engineering judgment to work with information that may be uncertain or incomplete, discussing the limitations of the techniques employed.

Select and apply appropriate computational and analytical techniques to model complex problems, discussing the limitations of the techniques employed.

Skills

Produce creative and realistic solutions to complex problems.

Support previously identified areas by using appropriate IT resources.

Analyse data using appropriate techniques.

Manage time effectively in order to achieve intended goals.

Assessment
