This paper presents a CFD numerical simulation method for ship E/R ventilation. Through the discretization of the fluid control equation, the basic physical model of the engine room is estab-lished by using GAMBIT software, and the air intake of the engine room is optimized according to the air supply quantity. The physical model is established into FLUENT, and the boundary condition, the solution method and the precision of the model are selected reasonably. Finally, the air flow distribution in different ventilation modes is taken as an example, and the characteristics of each scheme are compared and analyzed, and the optimal ventilation scheme is obtained. The method proposed in this paper has important theoretical and practical significance for optimizing the ventilation of the ship room.
