Experimental study on foaming mechanism of diesel oil during large-flow rapid refuelling process

摘要

Modern social life and the needs of industrial development has put forward higher requirements for the flow and efficiency of refuelling process. However, the greater the filling flow, the bubble produced by diesel oil is more obvious which will reduce the fuel efficiency seriously. This article focus on the influence factors and mechanism of diesel oil foam during large-flow rapid refuelling process by setting different condition of filling experiments. It was found that the filling Jhw rate of 150 L/min ～180 L/min is suitable for achieving the balance with the combination of consideration of refuelling rate and bubble reduction. What is more, the way of increasing the diameter of refuelling gun has obvious influence in diesel bubbles reduction. In addition, "flare regular" refuelling gun produce more bubbles than "straight regular" refuelling gun which is mainly because the diesel oil in the pipeline is more turbulent. The developed model and experiment results are useful to researchers and engineers in the area of large-flow rapid refuelling process of diesel oil.
