利用仿真建模软件对舰船密闭舱室与内部发热体用简化模型进行模拟。采用高Reynolds数k-ε模型与壁面函数法对舱室内空气湍流传热进行计算，分析同等送风量条件下不同送风方式以及不同送、回风口尺寸对舱室温度分布的影响。研究表明：采用下侧送风、上侧回风方式对舱室降温效果更好；回风速度与回风口尺寸对舱室温度无明显影响；送风速度小且送风口尺寸大时，舱室温度分层明显，整体温度更低。

By means of the modeling and simulation software,ship cabin and internal heating element were designed with simplified model.High Reynolds number k-εmodel and wall function method was used in-side the cabin turbulent heat transfer calculation.With different mode of air supply and different size of air intake and return under the same amount of air supply,the influence for cabin temperature distribution were analyzed.The studies indicate that with downside air intake and upside air return the cabin cooling effect is better,and the speed of return air and the size of air return have no obvious effect on the cabin temperature.While the speed of air supply is low and the size of air intake is large,the cabin temperature layer is obvious and the overall temperature is lower.
