For the vacuum cleaner of Prob. 1558, change to laminar flow instead of inviscid flow, and recompute

Question:

For the vacuum cleaner of Prob. 15–58, change to laminar flow instead of inviscid flow, and recompute the flow field. Compare your results to the inviscid flow case and to the potential flow case of Chap. 10. Discuss.

Data from Problem 15-58

Generate a computational domain and grid, and calculate the flow of air into a two-dimensional vacuum cleaner inlet (Fig. P15–58), using the inviscid flow approximation in the CFD code. Compare your results with those predicted in Chap. 10 for potential flow. Discuss.
