- Abstract
- An intumescent layer protects the underlying surface from fire thorugh the development of a thick char barrier in the presence of excessive heat. the effectiveness of these materials relies on the timing of certain critical chemical events. A three-dimensional numerical model that takes into account bubble hydrodynamics, heat transfer, and chemical reactions is being developed to aid in the design of these materials. The approach and implementation of this model are described and demonstrated.
