Question

A CFD model of steady two-dimensional incompressible
fl ow has printed out the values of stream function ψ ( x , y ), in
m 2 /s, at each of the four corners of a small 10-cm-by-10-cm
cell, as shown in Fig. P4.70. Use these numbers to estimate the resultant velocity in the center of the cell and its angle
α with respect to the x axis.

b = 1.9552 m²/s
2.0206
y = 1.1 m
V?
----
1.7308 m2/s
1.7978
y = 1.0 m
x= 1.5 m
x= 1.6 m
