I researched a hot-jet ignition of methane-hydrogen mixtures in a constant-volume combustor. According to the experimental data, I built a model for predicting the auto-ignition time as a function of the volume percentage of methane, volume percentage of hydrogen, main-chamber temperature, pre-chamber pressure, and equivalence ratio in the main-chamber, which will guide a Reactivity Controlled Compression Ignition (RCCI) engines with a pre-chamber.𝑬𝑵𝑮𝑰𝑵𝑬𝑬𝑹𝑰𝑵𝑮 𝑷𝑹𝑶𝑱𝑬𝑪𝑻 𝑬𝑿𝑷𝑬𝑹𝑰𝑬𝑵𝑪𝑬𝐀 𝐡𝐢𝐠𝐡-𝐬𝐩𝐞𝐞𝐝 𝐒𝐜𝐡𝐥𝐢𝐞𝐫𝐞𝐧 𝐢𝐦𝐚𝐠𝐢𝐧𝐠 𝐰𝐢𝐭𝐡 𝐚 𝐫𝐞𝐜𝐨𝐫𝐝𝐞𝐝 𝐟𝐫𝐚𝐦𝐞 𝐫𝐚𝐭𝐞 𝐨𝐟 𝐮𝐩 𝐭𝐨 20,833 𝐟𝐫𝐚𝐦𝐞𝐬 𝐩𝐞𝐫 𝐬𝐞𝐜𝐨𝐧𝐝 𝐭𝐨 𝐦𝐞𝐚𝐬𝐮𝐫𝐞 𝐭𝐡𝐞 𝐢𝐠𝐧𝐢𝐭𝐢𝐨𝐧 𝐦𝐨𝐦𝐞𝐧𝐭 𝐚𝐭 𝐚 𝐜𝐨𝐧𝐬𝐭𝐚𝐧𝐭-𝐯𝐨𝐥𝐮𝐦𝐞 𝐜𝐨𝐦𝐛𝐮𝐬𝐭𝐨𝐫 (𝐂𝐕𝐂)• Using the schlieren visualization technique to analyze the ignition event and determine the ignition time• Reporting the ignition delay data for a hot-jet ignition of methane-hydrogen mixtures in a constant-volume-combustor• Using the response surface methodology (RSM) to establish a correlation for the auto-ignition time that could represent all the operating factors
