Abstract: The surrogate fuel chemical reaction kinetic mechanism is widely used in computational fluid dynamics (CFD) model to improve the simulation accuracy. The present work developed a new surrogate fuels of heavy fuel oil. The new surrogate fuel includes eight components: C14H16, C16H34, C20H42, C21H44, C5H10, C7H8, C10H8, and C14H10, which were employed according to HFO's measured chemical composition. The newly developed mechanism includes 113 species and 418 reactions. The mechanism was validated with experimental data in shock tube. The surrogate fuel of HFO was chose by comparing heat release rate in fuel ignitability analyzer (FIA). The different ratios of components were researched in surrogate fuel. The surrogate fuel S6 was used as surrogate fuel of HFO. The surrogate fuel S6 of HFO was validated with experimental data in visual constant volume combustion chamber (VCVCC) and marine engine. Satisfactory prediction of spray and combustion development by the present model was shown by comparison with flame images from VCVCC experiments. Last, simulated in-cylinder pressure for a three-dimensional (3D) marine engine CFD model was consistent with experimental and one-dimensional (1D) results. Overall, the S6 mechanism can accurately simulate HFO combustion, bringing the simulation of marine engine a step closer.
