Aerodynamics: From Fundamentals to Applied Design

Course Modules & Syllabus

1. Module 1: Foundations of Fluid Mechanics and Flow Principles

   • Understand conservation laws (mass, momentum, energy) governing fluid flow and their mathematical formulation via Navier-Stokes equations
   • Distinguish between laminar and turbulent flow regimes using Reynolds number; apply dimensional analysis to aerodynamic problems
   • Analyze pressure, velocity, and streamline patterns in incompressible flow using Bernoulli's equation and continuity principle

2. Module 2: Aerodynamic Forces: Lift, Drag, and Thrust

   • Define and quantify lift and drag forces using pressure and shear stress distributions; relate to coefficient of lift (CL) and drag (CD)
   • Classify drag sources (pressure drag, skin friction drag, induced drag) and explain their physical origins in flow separation and boundary layers
   • Apply force balance equations to predict aircraft performance metrics (climb rate, cruise speed, stall conditions) in Nigerian airspace contexts

3. Module 3: Airfoil Theory and Wing Aerodynamics

   • Analyze airfoil geometry, angle of attack, and camber effects on aerodynamic performance using thin airfoil theory and circulation concepts
   • Interpret pressure coefficient (Cp) distributions and use them to predict stall behavior and optimal operating ranges
   • Extend 2D airfoil analysis to finite wing performance, accounting for induced drag via Prandtl's lifting-line theory and aspect ratio effects

4. Module 4: Boundary Layer Theory and Flow Separation

   • Characterize boundary layer development, thickness growth, and velocity profiles in laminar and turbulent regimes
   • Predict flow separation conditions using adverse pressure gradients; relate separation to form drag and aerodynamic stall
   • Apply boundary layer control techniques (e.g., trip wires, vortex generators) to enhance aerodynamic efficiency in practical designs

5. Module 5: Computational Aerodynamics and Numerical Methods

   • Formulate aerodynamic problems as computational fluid dynamics (CFD) simulations using discretization methods (finite difference, finite volume, finite element)
   • Execute CFD workflows: mesh generation, solver setup, convergence monitoring, and post-processing of flow fields and force coefficients
   • Validate computational results against experimental data and analytical solutions; assess mesh independence and numerical accuracy

6. Module 6: Experimental Aerodynamics and Wind Tunnel Testing

   • Design and conduct wind tunnel experiments to measure aerodynamic coefficients, pressure distributions, and flow visualization
   • Apply scaling laws and similarity principles to relate model-scale wind tunnel results to full-scale aircraft performance
   • Interpret experimental uncertainty, repeatability, and systematic errors in aerodynamic measurements

7. Module 7: Applied Aerodynamic Design and Performance Optimization

   • Integrate aerodynamic principles into aircraft design: fuselage shaping, wing planform selection, and control surface sizing for target performance
   • Optimize designs for competing objectives (e.g., fuel efficiency vs. climb performance) using trade-off analysis and parametric studies
   • Evaluate aerodynamic performance in realistic scenarios: takeoff/landing in Lagos airspace, cruise efficiency on regional routes, and crosswind handling

8. Module 8: Advanced Topics: Compressibility, Transonic Flow, and Special Applications

   • Extend incompressible aerodynamics to compressible flow regimes; apply Prandtl-Mach correction and shock-expansion theory for transonic aircraft
   • Analyze specialized aerodynamic phenomena: shock-induced separation, buffeting, and flutter instabilities relevant to high-speed flight
   • Apply aerodynamic principles to non-aircraft systems: vehicle aerodynamics for road transport, building aerodynamics in urban environments, and wind energy systems
