Velocity and Pressure Distribution in the Jet-Swirl Atomizer Chamber

Atomization of liquids has many applications and is very important for modern power engineering. The geometry of the atomizer and the boundary conditions are given in this paper. The most important is the momentum exchange between the axial and tangential components. As a result, the velocity and pressure distributions in the chamber of this atomizer are obtained. The CFX code with the k-ε model of turbulence was employed for this purpose. The Rossby number was taken as the similarity criterion to assure the similarity between the velocity distribution in the present work and in the experimental one carried out before.
