摘要
由于条件的限制,在实际的工程领域中,温度场建模被广泛地应用。影响温度场建模准确性的重要因素之一就是边界条件的确定,而在很多的工程应用中,边界条件不能通过实际测量得到。以海底敷设的复合海缆为背景,着重从理论上对海缆温度场的边界条件进行了研究和计算,然后通过温度场模型计算出来的铜芯温度与实际测得的海缆温度数据进行比较,从而来验证理论方法的正确性。结果表明所提出的理论计算方法计算出的结果与实际测量结果比较接近,最大误差小于2.49%,满足实际的工程需要。
Temperature field modeling is widely used in practical engineering fields because of the actual limited conditions. The determine of boundary condition is one of the most important factors influencing the accuracy of the temperature field modeling, which can＇ t be measured in many engineering applications. Based on composite submarine cable, the boundary condition of the submarine cable＇ s temperature field is studied and calculated in theory primarily. Then the correctness of the theory is verified by comparing the theoretical results with the actual measured cable temperature data. The result shows that the data obtained by theoretical calculation method are very similar with the actual measurement data, the maximum error is less than 2.49%, which can meet the needs of the actual project.
