摘要
为满足船用特种环形舱室内设备温度存储要求,运用数值模拟软件CFD建立模型,通过文献数据验证了模型的正确性,然后对特种环形舱室内温度分布进行数值模拟计算,分析特种环形舱室大气环境控制方案的结果。模拟结果表明原方案虽然考虑了高度较大所带来的气流不均的问题,采用中间送上下回的送风方式,但由于维修通道的存在阻碍了高度方向上的空气流动,在该方案下舱室上部区域温度超过30℃,原设计方案无法满足设备存储要求。经过方案改进,将维修通道改为船用格栅后,舱内平均温度为26℃,满足设备存储要求,相比原方案整体温度分布更加均匀,改进方案更具经济性,但存在舱外极端高温下舱内上部区域温度超标而报警的风险,后续建议通过设置扰动风机等方式进一步优化舱室大气环境控制方案。模拟结果为舰船特种环形舱室大气环境控制的设计优化提供了参考。
In order to meet the requirement of temperature storage in special annular cabin,the temperature distribution in special annular cabin was calculated by using CFD software,the results of air environment control scheme for special annular cabin are analyzed.The simulation results show that although the original scheme takes into account the problem of air flow unevenness caused by high altitude and adopts the air supply mode of sending up and down in the middle,the average temperature of the cabin is 29℃under this scheme,and the overall temperature is on the high side,there is a risk that the cabin temperature will exceed the standard and alarm under the extreme high temperature outside the cabin.The original design can not meet the storage requirements of the equipment.The average temperature in the cabin is 24.25℃,which meets the storage requirements of the equipment.Compared with the original scheme,the overall temperature distribution is more uniform,and the improved scheme is more economical.The simulation results provide a reference for the design optimization of the atmospheric environment control of the ship's special annular cabin.
