Comparison fine spray nozzle for two phase flow within experimental and simulation

The conversion of bulk liquid into fine spray is very important nowadays in several industrial process and has many application in agriculture, meteorology, and medicine. So, the design to develop a fine spray nozzle was varies according to the application. However, new development in fine spray noz...
