Question details

5. (10 pts) A CFD model of steady two-dimensional incompressible irrotational flow was used to solve two different problems. In case (a) the streamfunction values at the four corners of a cell were calculated. In case (b) the velocity potential values were calculated. See Fig. P5. Use these figures to estimate the resultant velocities at the center of the cell, and the angles with respect to the x-axis, for each case 1.9552 m2/s 2.0206 = 4.8338 m2/s 5.0610 Ψ y= 1.1 m y= 1.1 m V ? 1.7308 m2/s 1.7978 4.9038 m2/s 5.1236 y# 1.0m x 1.5 m x 1.6 m ,r = 1.5 m Figure P5.
