Topics

• Equations of fluid motion (Navier-Stokes) and exact solutions LO1–2
• Dimensional analysis, Buckingham Pi and similarity LO3
• Boundary layers: integral analysis, skin friction and drag LO4–5
• Laminar and turbulent flow; flow visualisation and measurement LO6

Learning outcomes

1. Explain the principles behind the general equations of fluid motion, incompressible and compressible
2. Simplify the equations in rectilinear and cylindrical coordinates and solve simple flows
3. Use Buckingham Pi to form dimensionless groups and apply similarity
4. Model boundary layers with integral analysis
5. Estimate skin friction and drag for aircraft, ships and vehicles
6. Describe laminar and turbulent flow, flow visualisation and turbulence measurement
7. Analyse head losses in pipes and flow distribution in networks
8. Calculate pressure and velocity changes in high-speed internal gas flow
9. Run a RANS simulation of turbulent flow
10. Present results to grant or tender formatting standards
