Flame spread over solid fuels in opposite natural convection

Upward Flame Spread Over Discrete Fuels

Title of Document: Upward Flame Spread Over Discrete Fuels Colin H. Miller, Master of Science, 2014 Directed By: Dr. Michael J. Gollner, Assistant Professor, Department of Fire Protection Engineering Upward flame spread over discrete fuels has been analyzed through experimental research on vertical arrays of alternating lengths of PMMA and insulation. By manipulating the lengths of the PMMA fue...

Radiation-Driven Flame Spread Over Thermally-Thick Fuels in Quiescent Microgravity Environments

Microgravity experiments on flame spread over thermally-thick fuels were conducted using foam fuels to obtain low density and thermal conductivity, and thus large spread rate (Sf) over thermally-thick fuels compared to dense fuels such as PMMA. This scheme enabled meaningful results to be obtained even in 2.2 second drop tower experiments. It was found that, in contrast conventional understandi...

Combined Radiation and Natural Convection in Participating Laminar Flow Over a Vertical Circular Pin

The interaction of thermal radiation with conduction and laminar natural convection in a vertical circular pin, situated at participating gas, is numerically investigated. An absorbing and emitting gas is considered, and treated to be a gray participating media. Under the idealizing of gray gas, the Rosselan4 approximation is employed to describe the radiative heat flux in the energy equation. ...

Natural convection solid/liquid phase change in porous media

A combined numerical and experimental study is reported of solid/liquid phase change in porous media with natural convection in the melt region. The model is based on volume averaged transport equations, while phase change is assumed to occur over a small temperature range. Experiments are performed in a vertical, square enclosure using gallium and glass beads as the fluid and the porous matrix...
