Experimental study on two-dimensional propagating edge flames: cold flow modeling and flame spread rate measurements
… propagating edge flames. The results were generated using a new apparatus in which a thin stream of gaseous fuel is injected into a low-speed laminar wind tunnel thereby forming a flammable layer along the centerline. The fuel injector consists of aluminum airfoil with a thin slot in its …

Composition Effects on Sheen and Spread Rate of an Interior Flat, One Coat Latex Paint Formulation
… interior flat, white latex paint that yields a spread rate of greater than 400 ft2/gal., which is advertised by many below critical pigment volume concentration (CPVC) commercial paints. In order to achieve this goal, an above CPVC paint with a high TiO2 content was created and continuously …

Calcium Carbonate Particle Size Effects on Titanium Dioxide Light Scattering in Coatings
… purpose of this study was to compare the coating spread rate of paints with varying TiO2 and CaCO3 pigment volume concentration (PVC). Different sized CaCO3 particles were used in this study. A series of PVC ladder studies were performed at keeping CaCO3 PVC constant. Paints were formulated at the …

The effect of physical properties on flame spread behavior for various paper/bagasse composition
… for paper production. However, research on flame spread towards combination paper / natural fiber is still a lack of data. Inspiration from this, the behavior of downward flame spread over paper and bagasse is experimentally investigated. This experiment was conducted by using the specimen with …

The Effects of Basin Slope and Boundary Friction on the Character and Plunge Location of Hyperpycnal Flows Entering a Laterally Unbounded Basin
… flows in the lateral y-direction, i.e. lateral spreading, in a three dimensional domain and to find out the parameters influencing the lateral spread. Previous studies conducted in laterally confined channels suggest that hyperpycnal flows plunge when the flow reaches a densimetric Froude number …

SPATIAL VARIABILITY IN FOREST FUELS: SIMULATION MODELING AND EFFECTS ON FIRE BEHAVIOR
… In the second chapter, this system is demonstrated in an exploratory simulation study which examines the impact of spatial variability within an individual tree crown on fire behavior. Results demonstrate that the distribution of fuel within a tree crown significantly affects the rate of fuel …

A LARGE EDDY SIMULATION STUDY OF THE EFFECTS OF WIND AND SLOPE ON THE STRUCTURE OF A TURBULENT LINE FIRE
… fundamental understanding of wildland fire spread is limited. Wildland fire spread is affected by many parameters, but two of the most important parameters are wind and slope both of which tilt the flame and plume and bring them closer to the unburnt fuel, which, among other things, …

Modeling full-scale fire test behaviour of polyurethane foams using cone calorimeter data
… modeling techniques to predict the heat release rate of the specimens, based on information obtained from cone calorimeter tests. Full-scale fire tests of 10 cm thick polyurethane foams of different sizes were conducted using center and edge-ignition locations. Flame spread and heat release rates …

Development of a new apparatus to measure flame spread through a free stratified fuel/air mixture: numerical modeling and experimental results
<p>While flame spread through uniform fuel-air mixtures has been widely studied in combustion science, there has been relatively little attention given to the study of non-homogenous, or layered, fuel-air mixtures. However, these systems are common occurrences in such cases as terrestrial fuel …

The reconstruction of fires involving highly flammable hydrocarbon liquids
… of the vapours from these fuels as they spread and diffuse. They are sometimes assumed to vaporize completely and instantly upon exposure and to diffuse uniformly through any compartment. The available models address large scale spills in ambient conditions of sun and wind, which do not …
