Two-stroke marine diesel engines (MDEs), having higher power output and higher efficiency, are widely
installed as a main engine in propulsion system of largest ships such as container vessels, bulk carriers, and
tankers. Most of numerical and experimental studies on two stroke marine diesel engines focused on
scavenging process because of critical importance of it. There are a limited number of studies that
considered compression, combustion and expansion processes of two-stroke marine diesel engines in
literature. Therefore, full-scale computational fluid dynamics (CFD) model of a two-stroke MDE were
developed by using ANSYS-Forte software in this study. Each step of CFD modeling approach was inclusively
described in the presented study. Cylinder pressure history was used to validate CFD model. Findings
showed that results of the numerical model were in good agreement with the experimental data.
