โœฆ Synopsis

The IV, u-dimensional laminar fire plume over a vertical burning surface was examined both theoretically and experimentally. The analysis involved numerical solution of the boundary-layer equations, using the similarity solution valid in the pyrolysis zone as an initial condition. Flame shapes were determined experimentally, using wicks soaked with methanol, ethanol, and I-propanol to simulate the burning portzon of the surf~e. Agreement between theory and experiment was reasonably good; flame lengths were predicted within 20'4 of the measurements. Greatesl errors were found for predicted flame shapes m the pyr~lysi~ rcgkm, where experimental difficulties in properly representing the leading edge and possible breakdown o! the boundary layer equations are ,tugge,tfed as factors contributing to the discrepancy

The steady two-dimensional flow of a gaseous fuel undergoing oxidation (burning) in the vicinity of a hot vertical wall is investigated for combined free and forced convection using the differential equations of continuity, momentum, energy, and species conservation. The equations are first reduced

A physical model for simulating combustion systems in laminar flow reactors has been developed. The one-dimensional model is derived from the conservation equations and thermodynamic relations, and includes transport phenomena. It is an extension of zero-dimensional models proposed by others, and e

A theoretical investigation of the ignition of a combustible gas by a heated vertical surface is described. Laminar, natural convection conditions were treated by numerical solution of the nonsimilar boundary layer equations, assuming an ideal gas and a one-step reaction and neglecting radiation. Th
