Analysis and Numerical Simulation of Internal Flow of Pressure Swirl Injector
, M.Sc. Thesis Sharif University of Technology ; Morad, Mohammad Reza (Supervisor) ; Kebriaee, Azadeh (Supervisor)
Abstract
In This thesis, the behavior of flow inside the pressure-swirl atomizers is studied. The pressure-swirl atomizers are widely used in many industrial applications such as fuel injection in gas turbine, internal combustion engine and liquid-fuel rocket, spray drying, spray in firing and agricultural nozzles.The flow simulation inside the pressure-swirl injector deals with many complicated considerations due to air core formation in the axial zone of the injector as well as high tangential and axial velocities in the swirl camber. The ANSYS Fluent commercial program is used for simulations. The two phase flow inside the injector is modeled by volume of fluid method (VOF) using large eddy...
