Abstract :Reduction of nitrogen oxide insert ignore into journalissuearticles values(NO x ); emissions from ships due to environmental pollution and greenhouse gas impact has been made obligatory by regulations introduced by the International Maritime Organization insert ignore into journalissuearticles values(IMO);. Basically, NO x emission control mechanisms are divided into primary methods and after-treatment methods. After-treatment methods focus on reducing NO x emissions from the exhaust gas by various methods. In this study, the efficiency of the urea transformation for different exhaust temperature values for a modelled Selective Catalytic Reduction insert ignore into journalissuearticles values(SCR); system has been investigated numerically. As a result of numerical model, isocyanic acid, temperature, urea and ammonia values have been determined for Urea-Water Solutions insert ignore into journalissuearticles values(UWS); process values. The study has been calculated by the computational fluid dynamics insert ignore into journalissuearticles values(CFD);. The numerical results obtained were confirmed by experimental studies from the literature.
