Develop a reasonable layout of nodes and control volumes for the geometry shown in the sketch. Provide a scale drawing showing the problem geometry overlaid with the nodes and control volumes.
GIVEN
Rectangular problem geometry
FIND
(a) A reasonable layout of nodes and control volumes
SKETCH
The largest node spacing divisible into both 3 and 10 is 1 cm. So let’s use ?x = ?y = 1 cm. The sketch on the right above shows the resulting placement of nodes and control volume boundaries.
