AERO4260: Aerodynamics 2

This unit aims to introduce students to: elementary and advanced topics in Gasdynamics (High Speed Flows). Course content will include review of Equations of Gasdynamics, One-Dimensional Gas Flow, Isentropic Flows, Normal Shock, Flow in a Converging and Converging-Diverging Nozzle, Steady Two-dimensional Supersonic Flow, Shock waves (Normal and Oblique), Method of Characteristics, Two-dimensional Supersonic Aerofoils, Introduction to Three Dimensional Effects, Unsteady Flows, Moving Shocks, Shock Tube Flow and Transonic Flow and Compressible Boundary Layers, introduction to turbulent flows. At the end of this unit the student will be able to calculate a high speed flow about an aerofoil and compressible flow through a duct of varying cross-section and will have a good appreciation of Transonic and Hypersonic Flows.

At the completion of this unit, you should be able to:

  • LO1. defend a specific choice of CFD method to compute a high speed flow
  • LO2. synthesise available information to determine which analytical approach and CFD method to apply in the analysis and optimisation of ducts, nozzles, intakes or aerofoils
  • LO3. describe qualitatively and evaluate a compressible flow through a duct of varying cross section, including the exiting plume, with or without heat addition or subtraction. Qualitatively describe duct flow with friction.
  • LO4. Derive and apply steady and unsteady isentropic flow analysis and application to one and two dimensional rarefactions. Understand assumptions and articulate the limitations.
  • LO5. Classify the three fundamental wave types present in compressible fluids. Understand the formation of a shock wave and how to compute post-shock properties of normal and oblique waves.
  • LO6. Understand and apply the fundamentals of numerical analysis, including stability, accuracy and convergence for upwind discretisations of the one dimensional linear advection equations. Appreciate the application of the method to second order in space and time schemes to solve the Euler equations.
