FLAIR Library case: Smoke in chimney (102).

1. Problem.


This case models a simplified transient two-dimensional chimney, described with the aid of Body Fitted Coordinates (BFC).

There is a small opening at the lower end of the chimney and the top is fully opened. A fire starts near the bottom end.

Geometry.

2. Results.

• Concentration contours every 100s.
• Velocity vectors every 100s.
• Pressure contours every 100s.
