Turbocharger matching for a high rated two-stage turbocharged Diesel engine is rather difficult due to the power balance between the two turbocharger stages. Compressor surge is a predominant factor, especially for naval applications for which operation ranges are quite wide. In this paper, a simulation study of a two-stage turbocharged system that includes a low pressure and a high pressure compressor is presented. Equations that are specific to such a system are added to a basic model and the resulting set of equations is solved using ACSL. The influence of the geometry of the charging air system on the compressor surge is analyzed according to the primary engine parameters (cylinder pressure, engine speed and distribution diagram)
