柴油、乙醇和水三组元乳化液流变特性的研究

研究了柴油、乙醇和水三组元乳化液的流变特性。实验发现乳化液在本文的组分配比下近似为牛顿流体,而且乳化剂的种类、含量以及乳化液的组分等均对乳化液的流变特性具有显著的影响。对于组分相同的乳化液,乳化液的粘度随着乳化剂含量和粘度的增加而增加;当乳化剂的含量和粘度相同时,若乙醇和水之间的相对质量分数保持不变,减少乳化液中柴油的含量(柴油不少于50％),乳化液的粘度随之增加。但是,柴油、乙醇和水三组元乳化液的粘度要比柴油、甲醇和水三组元乳化液的粘度大2到3倍。

STUDY OF RHEOLOGICAL CHARACTERISTICS OF THE EMULATIONS MADE OF DIESEL, ETHANOL AND WATER

Rheological characteristics of the emulations made of diesel fuel, ethanol and water are studied. The corresponding experimental results show that the emulations appear as proximately Newton fluids in the experimental composition. The rheological characteristics of the emulsions are significantly dependent on the different kinds and different percentages of emulsifying agents, and the composition of an emulsion has significant influence on oneself. For the emulsions with the same composition, the higher the percentage and/or the viscosity of emulsifying agent added into the emulsions is, the higher the viscosity of the emulsion is. If the ratio of ethanol to water in the emulsion is constant, the lower the percentage of diesel fuel is, the higher the viscosity of emulsion is, when the percentage and viscosity of the emulsifying agent is the same and the diesel fuel is more than 50% of emulsion. However, the viscosity of the emulation made of diesel fuel, ethanol and water is 2 to 3 times larger than that made of diesel fuel, methanol and water in the same composition.
