【摘要】 原油在管道流动过程中,摩擦力做的功转化为摩擦热,引起原油温度升高.根据流体热力学原理,建立了摩擦热影响下的非牛顿原油层流热力学模型,给出了埋地热油管道沿线温度的数值计算方法,确定了原油管道沿线温度.结果表明:当原油处于非牛顿层流状态时,摩擦热的影响不可忽略.更多还原

【Abstract】 When crude oil is flowing in the pipeline,work caused by friction is changed into friction heat,which causes oil temperature to increase in the pipeline.In this paper,the Laminar thermodynamic model of non-Newtonian crude oil has been established according to fluid thermodynamics theory.The numerical calculation method has been put forward for obtaining the crude oil temperature.The temperature distribution along pipeline is given.Friction heat of crude oil is obvious in non-Newtonian laminar flow,which can’t be ignored.更多还原
