摘要/Abstract

摘要： 在构建同轴静电雾化切削试验平台的基础上，以蓖麻油、大豆油、菜籽油、棕榈油、LB2000及其碳纳米管油基纳米流体为外流体，以去离子水及其碳纳米管水基纳米流体为内流体，分析了不同外流体基液类型下同轴静电雾化荷电性能和复合液滴电润湿性能，研究了外流体基液类型对纳米流体同轴静电雾化切削的切削力和温度的影响。结果表明：LB2000适合作为纳米流体同轴静电雾化切削的外流体基液，可有效减小切削力和降低温度，且以LB2000/水基纳米流体为外/内流体时，减力降温的综合效果最佳。

Abstract: Based on the construction of coaxial electrostatic atomization cutting test platform, taking castor oil, soybean oil, rapeseed oil, palm oil, LB2000 and its carbon nanotube oil-based nanofluid as external fluid, taking deionized water and its carbon nanotube water-based nanofluid as internal fluid, the charging performance of coaxial electrostatic atomization and the electrowetting performance of composite droplets under different types of base fluid of external fluid were analyzed. The effects of base fluid type of external fluid on the cutting force and temperature of nanofluid coaxial electrostatic atomization cutting were studied. Results show that LB2000 is suitable as the base fluid of external fluid for nanofluid coaxial electrostatic atomization cutting, which may effectively reduce the cutting force and temperature, and the comprehensive effects of force reduction and cooling are the best when LB2000/water-based nanofluid used as external/internal fluid.

Key words: nanofluid, coaxial electrostatic atomization, charging performance, electrowetting performance, atomization cutting
