Comparison of the Characteristics of Sprays between Water and Nanofluid Sprays
Journal of ILASS-Korea, 2014 Abstract Nanofluids is that metallic or nonmetallic nanometer-sized particles are dispersed in liquid and they can be used in variousfields to increase the heat transfer rate. This study conducted experiments to evaluate whether the cooling efficiency of nanof-luids is better than that of water in spray cooling.

Analysis of Spray Flow Pattern and Spray Combustion Characteristics.
Journal of the Fuel Society of Japan, 1991 The analysis of spray flow was very important for the spray combus-tion simulation. In this study, the models for the spray pattern and the motion of spray dro-plets in the gas flow were investigated to improve the simulation accuracy. The spray pat-tern was expressed by the random sampling of spray angles from a normal probability de-nsity ...
