- Abstract
- A theoretical and experimental study is made of the factors influencing the burning rate between two vertical parallel fuel surfaces facing one another. No radiation, infinite gas phase reaction rates and unit Lewis number are assumed. The equations are solved numerically and the burning rate is found to be controlled by the product of Grashof number and channel aspect ratio (i.e., the half channel width divided by its length). For a wide channel separation, the burning rate is independent of the channel separation distance and the results reduce to our previous solution for single surface burning. For very long narrow channels the burning rate becomes independent of the channel length and asymptotically approaches an analytical solution for infinitely long channels. Finally, the theoretical results are compared to the experimental data with favorable agreement.
