Abstract

This chapter is proposed to solve the insufficient MQL cooling and heat transfer capability based on the heat transfer enhancement theory of solid. Adding nanoparticles into the base fluid can significantly elevate heat conductivity coefficient of the base fluid and enhance convective heat transfer capability of the grinding area. Researchers have carried out numerous experimental studies on nanofluids with different concentrations. However, the scientific nature of MQL cooling has not been explained. Degradable, nontoxic, low-carbon, and environmentally friendly green grinding fluid, palm oil taken as the base fluid, grinding force, grinding temperature and proportionality coefficient of energy transferred to workpiece of nanofluids with different volume fractions, are investigated in this chapter. Based on the analysis of the influence of physical characteristics of nanofluids on experimental results, cooling and heat transfer mechanism of NMQL grinding is studied. The experimental study can provide a certain technical guidance for industrial machining.

不同浓度纳米流体物理性质对磨削温度影响的实验研究

本章是基于固体强化传热理论，针对MQL冷却换热能力不足的问题提出的解决方案。在基液中加入纳米颗粒可以显著提高基液的导热系数，增强磨削区域的对流换热能力。研究人员对不同浓度的纳米流体进行了大量的实验研究。然而，MQL冷却的科学性质尚未得到解释。本章研究了以棕榈油为基液的可降解、无毒、低碳、环保的绿色研磨液，以及不同体积分数纳米流体的研磨力、研磨温度和向工件传递能量的比例系数。在分析纳米流体物理特性对实验结果影响的基础上，研究了NMQL磨削的冷却传热机理。实验研究可为工业加工提供一定的技术指导。
