Abstract

Semianalytical expressions are developed for creeping flame spread parallel to a fuel cylinder axis so that spread rates measured or predicted for flat surfaces over the same material can be directly used for cylindrical surfaces. Two phenomena are identified that cause an increased flame spread rate in the cylindrical over the flat surface geometry: i) increased heat transfer from the gas phase and ii) faster temperature increase of the solid phase. Results compare favorably with numerical solutions for cylindrical spread in forced and natural flows and microgravity and with experiments on downward flame spread on cylindrical rods in normal gravity and microgravity.
