Repeat Prob. 15–32, except use an unstructured triangular grid, keeping everything else the same. Do you get the same results as those of Prob. 15–32? Compare and discuss.

Data from Problem 15–32

Generate a computational domain to study ventilation in a room (Fig. P15–32). Specifically, generate a rectangular room with a velocity inlet in the ceiling to model the supply air, and a pressure outlet in the ceiling to model the return air. You may make a two-dimensional approximation for simplicity (the room is infinitely long in the direction normal to the page in Fig. P15–32). Use a structured rectangular grid. Plot streamlines and velocity vectors. Discuss.
