船舶机舱内热环境数值模拟

Numerical simulation of the internal thermal environment of marine engine room

采用计算流体力学的方法对已有机舱热环境进行数值模拟,使用计算流体力学软件FLUENT对机舱内温度场与速度场的三维分布进行数值计算,根据计算结果提出机舱通风的改进意见.研究结果可为船舶机舱通风系统设计提供理论依据,并对优化设计具有指导作用.

This paper used the computational fluid dynamics（CFD） method to evaluate the indoor thermal environment of an original designed marine engine room. The CFD software FLUENT was applied to calculate the 3D airflow and temperature fields of the engine room.The improvement suggestions on engine room ventilation are given according to the calculation results,which can provide theoretical basis for ventilation design of marine engine room and has guiding significance for optimizing the design scheme.
