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 8
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 10
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 9
Horizontal and vertical axis machines-energy density of different rotors-Power coefficient-
Betz coefficient by momentum theory.
UNIT IV BUILDING AERODYNAMICS 8
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 10
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.
