This study experimentally investigates the mechanism of the ignition of the supersonic liquid fuel jet by the visualization. N-Hexadecane having the cetane number of 100 was used as a liquid for the jet in order to enhance the ignition potential of the liquid fuel jet. Moreover. the heat column and the high intensity CO 2 laser were applied to initiate the ignition. https://balboasurfandsstylers.shop/product-category/cups/
