Numerical Predictions of Internal Flow through Pressure Swirl Atomizer

摘要

Pressure swirl atomizers are used in a wide range of applications. The three dimensional model of atomizer is numerically investigated with the primary focus of the analysis on the internal flow characteristics in the pressure swirl atomizer. The variation of the pressure x, y and z-component of velocity along the length of the pressures swirl atomizer has been studied at different injection pressure of 6, 9, 12, 15 and 18 bar using commercial CFD code. The two-fluid Euler/Euler method is considered for the flow inside the atomizer.
