Topic 1: Introduction to aerodynamics – meaning and history Development of aerodynamics in transport, basic concepts and motivations for improving vehicle shapes.
Topic 2: Introduction to aerodynamics – physical nature of flow Basic quantities (speed, pressure, density), action of forces, equilibrium of flow around bodies.
Topic 3: Aerodynamic forces
Drag, lift, downforce – their origin, decomposition and influence on vehicle driving characteristics.
Topic 4: Fundamentals of flow
Bernoulli equation, streamlines, pressure distribution, basic flow models.
Topic 5: Flow regimes and Reynolds number Laminar and turbulent flow, characteristic areas, transient phenomena.
Topic 6: Body shape and air resistance
Basic types of flow around a vehicle, influence of the front surface and shape of the rear part.
Topic 7: Pressure field around the vehicle
Distribution of overpressure and underpressure, formation of wake, interaction with the surrounding flow.
Topic 8: Wings, spoilers and flow guidance Principle of downforce generation, relationship between drag and stability, examples of shape solutions. Air guidance to the engine, brakes and interior, effect of openings on drag and cooling efficiency.
Topic 9: Aerodynamics of railway vehicles I – basics Air drag in trains, importance of frontal shape, effect of train length and distances between cars.
Topic 10: Aerodynamics of railway vehicles II – operational phenomena Crossing trains, pressure waves in tunnels, lateral vortices and effect on passenger comfort.
Topic 11: Validation and testing
Basic principles of calculation verification, wind tunnel tests, pressure measurements, validation of numerical simulations.
Topic 12: Energy and environmental implications of aerodynamics The influence of drag on energy consumption, range, noise and emissions; the relationship between aerodynamics and transport efficiency.
Topic 13: Current and future trends in transport aerodynamics Active and adaptive aerodynamics, sensor integration, new concepts for electric vehicles and high-speed rail.
