This paper provides the methodology to achieve pseudo 1-D combustion system of specific polymeric materials without any complex physical effect (e.g., deformation, bubble bursting etc.) by adopting a low pressure technique with a fuel-layered approach. The adopted pressure level in this study is as low as 20 kPa and the size of the specimen is sub-millimeter scale. By utilizing pressure modeling to keep the Grashof number small, the gravity effect is relatively minimized at low pressure to mimic...

Fingering pattern formation of flame spread over a thick solid has been observed recently. Since the oxygen-enriched atmosphere in microgravity promotes the occurrence of fingering and thus it leads to a fire in space, it is important to understand the mechanism. Motivated by this, a previous study attempted to validate a similarity to smoldering fingering. However, it remains controversial because the quantitative evaluation of the fingering pattern was not satisfactory done due to the experime...

This paper provides alternative methodology to reproduce the smoldering of a 2-mm dia biomass stick in reduced gravity by utilizing a reduced-pressure approach. Since smoldering has been known as an initial process of fire hazard, a deep understanding of its characteristics is an important task to improve fire safety strategy in space. The aim of the present work is to examine the possibility to reproduce the smoldering in microgravity by utilizing the low pressure. The smoldering behavior and t...

Abstract Features of one-dimensional combustion-wave propagation of activated carbon particles (~ 1mm) packed in a quartz tube was examined experimentally. Rich oxygen was introduced into the tube to promote the surface oxidation of the activated carbon particles. An oxidizing mixture flows through a vertically placed quartz tube (from bottom to the top). Followed by the ignition at the top, hot reactive zone propagates downwardly with negligible regression of the specimen, so called “flame spre...

Abstract The smoldering behavior of porous combustibles near the extinction limit was examined under a highly-vacuumed environment at various oxygen concentrations. The considered ambient conditions of the present work is 1.0–90 kPa in absolute pressure filled with a nitrogen–oxygen mixture. A 2-mm-rod-shaped incense stick is considered as the burning specimen. The specimen was located vertically and forced ignition was made at the top of the specimen to complete the following downward propagati...

Abstract This systematic experimental study measures the effect of flame propagation along vertical edges on the overall downward spread of flames using Polymethyl Methacrylate (PMMA). Samples with a wide range of regular cross-sections – from triangular through octagonal – as well as irregular ones, have been used to test a large variation of internal angles. A MATLAB-based tool was used to calculate instantaneous spread rate for central and edge flames. The edge flame is shown to significantly...
