The effect of catalytic reaction oh Hot surface ignition

摘要

The hot surface ignition of methane-air mixtures in microgravity has been studied experimen- tally and numerically. Experiments on the ignition of the mixtures with electrically heated nickel wire and platinum wire in microgravity have been performed. Numerical calculations, including the catalytic reaction rate for platinum, have been performed to understand the experimental results obtained in microgravity. The ignition delays and ignition temperatures for a wide range of equivalence ratios were investigated.
