Consider the velocity field of Problem 2.18. Plot the streakline formed by particles that passed through the point \((1,1)\) during the interval from \(t=0\) to \(t=3 \mathrm{~s}\). Compare with the streamlines plotted through the same point at the instants \(t=0,1\), and \(2 \mathrm{~s}\).

Data From Problem 2.18

Transcribed Image Text:

2.18 Consider the flow described by the velocity field V = Bx(1+At)+ Cy, with A=0.5 s and B=C=1 s. Coordinates are measured in meters. Plot the pathline traced out by the particle that passes through the point (1, 1) at time t = 0. Compare with the stream- lines plotted through the same point at the instants t = 0, 1, and 2 s.
