摘要:
基于熵产率最小化原理，分析了原油在输送过程中散热损失和摩擦阻力引起的熵产情况，优化了熵产率最小所对应的管输起始加热温度。研究结果表明：最小熵产率与输送流量、起始温度和管道管径有关，输量对熵产率有一定的影响，输量越高，输送单位质量原油的熵产率越低，但随输量的增加，熵产率降低的幅度逐渐减少；只有适当的起始加热温度才能保证单位质量原油输送单位距离所产生的熵产率最小；对应最小熵产率的原油起始温度随管径的增大而降低。最小熵产率优化设计方法克服了热经济设计方法需要材料价格、施工费用等参数难于准确选取和所得结果与当前物价及贷款利率有关的缺点。
Abstract:
Based on the theory of minimizing entropy generation rate，the entropy generation caused by heat loss and frictional resistance of heavy oil in pipeline is analyzed. The initial heating temperature of pipeline is optimized when entropy generation rate is minimum. The result indicates that the minimum entropy generation rate is connected with the mass flow rate，initial temperature and pipeline diameter. The relationship between the flowrate and entropy generation rate is that the higher the flowrate is，the lower the entropy production rate is when the crude oil per unit mass is transported. However，with the increase of transport capacity，the reduce rate of entropy production rate is decreased. Only the appropriate initial heating temperature can ensure the minimizing entropy generation per unit mass and distance during the transportation. With the increase of pipe diameter，the initial heating temperature of crude oil corresponded with the minimum entropy generation rate is decreased. The optimization design method of entropy generation minimization overcomes the shortcomings of design method in thermal economy optimization which needs the parameters in material prices，construction costs and something like that difficult to determine，and the result is affected by the price levels and interest rates.
