5. Eulerian modeling

The complexity of the atomization process raises the question of the need for detailed modeling of drop formation. A global representation providing averages and variances of sizes, velocities and other characteristics of the two-phase flow would suffice to dimension atomizers and meet most requirements in this field. The difficulty in this case is to formulate the effects of liquid break-up in a comprehensive way. An effective model is that developed in by Vallet and Borghi, outlined below.

Based on the equations of viscous compressible fluid flow, averaged according to Favre's method, we don't distinguish...
