| The main purpose of ventilation in marine engine room is to set up and maintain a suitable circumstance (temperature, humidity, velocity, purity) both for the engines and engineers. It also can avoid some accidents that are brought owing to gather of gas of oil. Present ventilation Design of marine engine room depends on experience instead of specific method. Effect of ventilation of engine room doesn't be known until ship is build. Inlet of ventilation can reasonable arranged and wind flux can be distributed if ventilation of engine room is know before ship is build in order to form a good structure of airflow thereby gaining a good purpose of ventilation. This article use condition ventilation for reference to study engine room of container ship applying CFD technique. Field of velocity and temperature in engine room are obtained through simulation of ventilation of engine room. Inlet of ventilation and distribution of wind flux in according to the result. That offers a method of design of ventilation of engine room. The main works includes in the thesis are as followed1. Introducing ventilation of engine room and establishing aim of task.2. Some basis elements of the turbulence flow and heat transfer are discussed in detail and build relevant math model.3. The flow model of the engine room is calculated by applying of PHOENICS. Anglicizing result and mending reasonless place. |
