摘　　要：基于不可逆热力学的基本原理,根据管输原油的熵产率方程选择合适的"流"与"力",并利用居里原理确定可以耦合的"流"与"力",建立热质耦合的唯象方程组,结合实际物理过程确定各唯象系数的表达式并研究其变化规律。研究成果为建立基于不可逆热力学的蜡沉积模型,进而深入研究原油管道蜡沉积规律提供理论基础。Based on the basic principles of irreversible thermodynamics,appropriate “flow” and “power” were selected by using the entropy production rate equations of pipeline transportation crude oil,and according to the Curie principle ,the “flow” and ＂power＂ which can be coupled were determined, the phenomenological equation set of heat and mass coupling was established.The expression of each phenomenological coefficient was determined and the change rule was studied combined with the actual physical process. The research results obtained can provide the theory instruction for the establishment of wax deposition model based on irreversible thermodynamics and further study of wax deposition in crude oil pipeline.
