| 摘 要： | 含蜡热油管道在设计及实际运行过程中,油品密度、粘度、比热容沿程随温度变化,沿线流型与流态也不断变化,这些都是计算管道温降必须考虑的因素.从能量方程出发,计入析蜡潜热的影响,推导出管道沿线流量变化不大时的瞬态温度方程,并利用三特征线方法进行求解,提高了含蜡热油管道的计算精度,并为其设计计算及仿真软件的开发提供了理论依据.

| Abstract: | The density,viscosity and heat capacity of waxy crude oil is changed along with the temperature drop and flow type and the flow patterns are different along the pipe during the design and operation. Considered the above factors,the pipeline is divided into some nodes to calculate the steady temperature drop.Take the latent heat of wax crystallization into account,the equation of the transient temperature is deduced under the condition of less change of rate of flow based on the energy equation,and resolved by the three-characteristic line method.This method is of high calculation precision,which can be taken as a theory foundation of design and simulation of pipeline. |
