Abstract:

The paper presents a CFD numerical simulation method for ship engine room ventilation. First, through the discretization of the fluid governing equations, apply the basic physical model of ship engine room established by GABIT Software to lay out the engine room outlet according to the air supply and then divide the meshes. After the physical model is established, import the FLUENT and then reasonably choose the boundary conditions, solving methods and solving precision. Finally, obtain the optimal scheme by the example of researching the airflow velocity, temperature and humidity distribution under different ventilation schemes, and compare the characteristics of various schemes. The method presented in the paper has a strong significance of theoretical analysis and practical guidance for optimizing the ventilation of the ship engine room.
