Wax deposition model of marine fuel oil flowing in mobile pipeline
Marine fuel oil is for large naval vessel,which are the main naval combat vessels.Fuel oil has a high wax content,so in wartime and emergency situations,it is necessary to use the dockless oil replenishment system on shoreline based on mobile pipeline to replenish oil for combat ships.In the process of heating transfer marine fuel oil by mobile pipeline,the wax deposition in the pipeline is a serious problem due to the effect of low temperature and strong heat transfer in winter(mobile pipeline is laid bare on the ground),which seriously affects the normal work of oil supply system.In view of the need of wax deposition control in the process of mobile pipeline transportation of marine fuel oil,combined with the characteristics of mobile pipeline,the corresponding calculation model of flow,heat transfer and mass transfer was established,and the distribution law of wax deposition layer was obtained,the mechanism of wax deposition was clarified,so as to obtain the distribution law of wax deposition in mobile pipeline more accurately and provide strong technical support for the efficient operation of heating transfer marine fuel oil in mobile pipeline.
