Air movements through horizontal openings in buildings: a model study.
Author(s) : BLOMQVIST C., SANDBERG M.
Type of article: Article
Summary
Reports on an experimental study of the possibility of using buoyancy forces to distribute air and heat through horizontal openings. Focuses on air movements through horizontal openings, such as stairwells. The experiments have been carried out in a scale model with water as the operating fluid. The result of the study shows that the flow rate through a horizontal openings is approximately half of the flow rate through a vertical opening for the same conditions, probably caused by the more complex flow pattern in the horizontal opening. A staircase below the horizontal opening will guide the flow somewhat and will cause a small increase of the fluid exchange through the opening.
