Abstract

Atomization process is about converting volume of fluid into a multiplicity of small droplets, and twin fluid atomizers are more efficient in this aspect if the uninterrupted fluid flows are involved. The present numerical study is focusing on atomization of liquids (ethanol and water) by air with flow blurring injector at air to liquid ratio by mass of 2. The numerical simulation was carried out with commercial solver Ansys Fluent by using multiphase volume of fluid method (VOF) with large eddy simulation(LES). The uniform grid of minimum cell size of 2.5 micron was chosen after grid analysis of different sizes. The difference in air penetration length in the fuel tube, drop size distributions was observed through the numerical simulations for ethanol and water.
