A comprehensive study on the flame propagation of the horizontal laboratory wires and flame-retardant cables at different thermal circumstances
TL;DR: In this article, the influence of ambient temperature and incident heat flux on the horizontal flame spread over wires and cables was investigated, and it was shown that the flame spreads evenly along the wire, and the flame spread rate slightly increases with the ambient temperature increasing with a maximum increase of 16 %.

Influence of air gap ratio of the Chinese historical wooden window on the vertical flame spread performance
TL;DR: In this article , the authors investigated the influence of air gap ratio on the fire propagation mechanism of wooden windows by experimental investigating flame characteristics such as mass loss rate (MLR), flame spread rate (FSR), total burning duration (TBD), and maximum flame length (MFL).

Properties of wood for combustion analysis.
TL;DR: A systematic compilation of 21 different property values of wood and bark fuel was made to facilitate the engineering analysis and modeling of combustion systems as discussed by the authors, where the properties such as density, porosity, and internal surface area are related to wood species whereas bulk density, particle size, and shape distribution are related with fuel preparation methods.

Controlling Mechanisms of Flame Spread
TL;DR: In this paper, heat transfer and gas phase chemical kinetic aspects of the flame spread process are addressed separately for the spread of flames in oxidizing flows that oppose or concur with the direction of propagation.

Flame spread in an opposed forced flow: the effect of ambient oxygen concentration
TL;DR: In this article, the velocity of flame propagation over the surface of thick PMMA and thin paper sheets has been measured as a function of the velocity and oxygen concentration of a forced gas flow opposing the direction of the flame propagation.

A simplified theory for generalizing results from a radiant panel rate of flame spread apparatus
TL;DR: In this paper, a simple theroretical model was proposed to analyze the rate of lateral flame spread and time for piloted ignition under an externally imposed radiant flux. But the model was applied to a single flame spread experiment.
