Convective acceleration
During a wind tunnel test on a sphere of radius r = 150 mm it is found that the velocity of flow u along the longitudinal axis of the tunnel passing through the centre of the sphere at a point upstream which is a distance x from the centre of the sphere is given by where Uo is the mean velocity of the undisturbed airstream.

An engineer is measuring the lift and drag on an aerofoil section mounted in a square wind tunnel. The wind tunnel is 0.5 m high and 0.5 m deep into the screen). The upstream air velocity is uniform at 25 m/s. The downstream velocity is uniform at 28.75 m/s in the lower half of the wind tunnel. The downstream velocity in the upper half is uniform. The vertical component of velocity is zero at the beginning and end of the...

A turbojet engine in a wind tunnel receives air at a velocity of U;= 100 m/s and a density of p.= 1 kg/m'. The velocity is uniform and the cross-sectional area of the approaching stream which enters the engine is A = 0.1 m². The velocity of the exhaust jet from the engine, however, is not uniform but has a velocity which varies over the cross-section according to: u. = 2U (I-YIR) where the constant U= 600 m/s and R...
