Combustion Process Analysis of Hydrogen/Diesel Dual-Fuel Engine by Numerical Simulation

Abstract

Hydrogen is mentioned as a power source toward carbon neutrality, and dual-fuel combustion system is effective to apply hydrogen to engine system because of its redundancy. In order to improve performance and avoid abnormal combustion of hydrogen engines, it is necessary to clarify the combustion forms. In this study, the analysis of hydrogen/diesel combustion process was carried out by using the hydrogen/diesel dual-fuel engine and conducting 3D-CFD calculations based on experimental results.
