CFD SIMULATION OF INJECTED FUEL SPRAY IN MARINE DIESEL ENGINES

Ph. D. Student Mahran Dawwa

Abstract :

<p> This paper discusses the simulation of injection process in marine diesel engines by the use of computational fluid dynamics method (CFD). The fuel injection process has a huge impact on the diesel engine parameters, and due to the raise in concern about reducing gas emissions and improving the fuel economy of marine diesel engines, the concentration about improving the fuel injection process has increased. Hence, many researches and studies have been carried out for modeling and simulating the injection process in order to enhance the mixture formation inside the combustion chamber. Diesel spray is subjected to different physical processes (penetration, primary eak–up, and secondary eak–up) which will be explained and illustrated in details. The simulation in this study was carried out by the use of technical data of Hino W04D high speed marine diesel engine and ANSYS simulation software codes.</p>
