Laminar burning velocity of hydrogen and carbon-monoxide enriched natural gas (HyCONG): An experimental and artificial neural network study

The laminar burning velocity of H2 and CO enriched natural gas (HyCONG) mixtures measured through spherically expanding flames method under three different fuel-air equivalence ratios (0.6, 0.8, and 1.0) at room temperature and atmospheric pressure. Experiments have been conducted into constant volume combustion chamber by using high-speed schlieren photography technique. The five different CO fraction (0%, 20%, 40%, 60%, and 80%) and three HCNG...
