| Abstract: | 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. |
