【摘要】 本文采用理论分析、实验验证和实船应用检验相结合的方法,针对大连远洋运输公司的 68000DWT双壳体原油轮,油舱货油加热的经济方式进行了分析研究。根据非稳态导热集总参数法建立油轮油舱加热数学模型,研制了油轮货油加热计算软件。实验验证了计算软件所选用的传热模式是正确的,理论分析和实验表明在油轮加热过程中,货油内部主要的传热方式是自然对流。通过实船应用比较,软件计算的加热时间和实际的加热时间的最大误差是8％;计算的温度场与船舶实际温度场的最大误差为±2℃。更多还原

【Abstract】 An oil heating method of the 68000DWT double hull oil tanker is studied by means of combination of theoretatical analysis, experimental validation and application verification. The oil tanker heating model is established and the software is developed based on transient heat conduction gathered parameter method. The validity of heat transfer model used in the software is proved by experiment. Theoretatical analysis and experimental study show that in the oil heating process, natural convection is the dominant heat transfer style. The application shows that the max deviation of calculated heating time is 8%. Compared with measured value, the max deviation of calculated oil temperature field is ±2℃更多还原
