Abstract EN
Cutting mixed oil in product pipelines has a great influence on the economy of the pipeline operation processes.
The reasonable prediction of CDMS (the concentration distribution in the mixed segment) is important for cutting mixed segments.
The classical model cannot explain the tailing phenomenon well which should not be neglected during operation processes.
Based on Fick’s diffusion law, a new model for calculating the diffusion coefficient is proposed in this article, which originates from the essence of the diffusion phenomenon and considers the effects of both physical properties of oil products and the turbulence.
At the same time, the dynamic fluid equilibrium model of CDMS near the pipe wall is given which has considered the adsorption effect of wall roughness.
Based on these two factors, a novel numerical model for simulating the quantity of tailing oil is proposed, which is solved via the characteristic method and the finite difference method.
The effects of different physical properties, as well as the adsorption, on both LFMS (the length of the front of the mixed segment) and LTMS (the length of the tail of the mixed segment), are analyzed.
The comparison between the simulation results and the experimental data is utilized to validate the proposed numerical model.
The simulation results show that the novel model can well describe the mixed segment tailing phenomenon and also explain the mixing essence of two miscible but dissimilar fluids in the pipeline more clearly.
To sum up, this model can provide theoretical guidance for the prediction of CDMS and cutting process in practical operation processes; therefore, more economic benefit can be obtained.
