摘要：

Developments in the area of nano-fluids are ongoing specifically in the area of liquid-liquid extractions in different industries. In the present study, mass transfer coefficients have been obtained experimentally in a spray extraction column in the presence of different nano-particles to develop a new correlation for the prediction of the dispersed phase Sherwood number. The results have shown that the proposed correlation can estimate the experimental drop Sherwood number with high accuracy. Also, the conceptual effect of nano-particle hydrophobicity/hydrophilicity is quantified in correlation without which the experimental data could not be fitted with an acceptable accuracy.
