AE2026 INDUSTRIAL AERODYNAMICS class notes and last year question paper



AE2026 INDUSTRIAL AERODYNAMICS


OBJECTIVE:
To familiarize the learner with non-aeronautical uses of aerodynamics such as road vehicle, building aerodynamics and problems of flow induced vibrations.


UNIT I   ATMOSPHERIC BOUNDARY LAYER
Atmospheric circulation-Local winds-Terrain types-Mean velocity profiles-Power law and logarithm law- wind speeds-Turbulence profiles-Roughness parameters-simulation techniques in wind tunnels


UNIT II BLUFF BODY AERODYNAMICS
Boundary layers and separation-Two dimensional wake and vortex formation-Strouhal and Reynolds numbers-Separation and reattachments-Power requirements and drag coefficients of automobiles-Effects of cut back angle-aerodynamics of trains.


UNIT III WIND ENERGY COLLECTORS
Horizontal and vertical axis machines-energy density of different rotors-Power coefficient- Betz coefficient by momentum theory.

UNIT IV BUILDING AERODYNAMICS
Pressure distribution on low rise buildings-wind forces on buildings-Environmental winds in city blocks-special problems of tall buildings-building codes-ventilation and architectural aerodynamics


UNIT V   FLOW INDUCED VIBRATIONS
Vortex shedding, lock & effects of Reynolds number on wake formation in turbulent flows - across wind galloping-wake galloping-along wind galloping of circular cables-oscillation of tall structures and launch vehicles under wind loads-stall flutter.
