摘　　要：应用计算流体力学软件Fluent,基于多相流VOF模型,进行加油枪加油时有、无整流管两种状态的模拟,得出的油箱内油气体积分数云图表明:加装整流管加注时油箱内流场更加稳定,产生的气泡更少。通过柴油加注试验,对比分析加油枪有、无整流管两种情况,得到不同加油阶段油液状态的图像,由此表明整流管有较好的整流效果,可有效减少油液面上油沫的产生。最后总结研究结论并对整流管的使用提出了建议。The numerical simulation software Fluent is used to simulate the refueling process based on the multiphase flow’s VOF model, which both cases of the refueling nozzle assembled and unassembled with rectifier tube, from that the contours of oil vapor volume fraction in the fuel tank show that the flow field is more stable and air bubbles are less generated in the fuel tank when the refueling nozzle is assembled with rectifier tube. Then via diesel refueling experiment, images of oil state in different refueling period are obtained, in both cases of the refueling nozzle assembled and unassembled with rectifier tube, which indicate that the recti-fier tube works better on rectifying, and can reduce the bubbles on the surface of the oil effectively. Finally research conclusions are summarized and suggestions on the use of the rectifier tube are put forward.
