Effect of Parallel Curtain Walls on Upward Flame Spread Characteristics and Mass Loss Rate Over PMMA

The effects of parallel curtain walls on the characteristics and mass loss rate upward flame spread over polymethyl methacrylate (PMMA) have been experimentally studied. experimental research variables were sample size separation distance wall. In setup, a PMMA plate was attached to one walls. results analyzed assess effect wall height. special condition two with only small between them also analyzed. Analysis experiments systematically varied distances has provided insight into factors such as air entrainment chimney effect. show height evolution trend distance, new correlation predict global under influence walls, which can potentially be used in design through optimization given fire safety requirements practical needs.Graphical Abstract
