Abstract

In this work, as a case study, the measurement of the density (ρ) and the dynamic viscosity (µ) of 12 different fluids (taken from a conventional oil mill) has been carried out. The variability of the samples processed shows that their impurity contents c (between 0.5-5.87%), together with the temperature t (which varied between 20-30 ºC), can affect the values of ρ and µ. However, this variation has been shown to be different depending on the case, being of the order of 1% for density or even more than 50% for dynamic viscosity. The fact that µ can be sensitive to the presence of impurities opens up a line of study that could be used to estimate such impuritiy content, in real time, by means of relatively simple methods.

杂质含量对橄榄油液体密度和粘度的影响

在这项工作中，作为一项案例研究，对 12 种不同流体（取自传统碾油机）的密度 (ρ)和动态粘度 (µ) 进行了测量。所处理样品的变化表明，其杂质含量 c（在 0.5-5.87% 之间）和温度 t（在 20-30 ºC 之间变化）会影响 ρ 和 µ 值。µ 对杂质的存在很敏感，这一事实开辟了一条研究思路，可以通过相对简单的方法实时估算杂质含量。
