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.
