What is it about?
This work is based on the optimization of small-scale sprayers in the field of household/cleaning products. We analyze the effects of the hollow-cone destabilization in terms of ligaments/droplets propagation together with their impact against a surface located far from the liquid ejection. We show that nozzle design and fluid properties do affect the hollow-cone primary atomization in terms of spray pattern and particle size distribution.

Why is it important?
Compared to the actual field of the research advancements, we exploit an innovative CFD model to predict and recognize specific fluid dynamics phenomena that can describe the operability limits of Newtonian and non-Newtonian hollow-cone sprays.
Perspectives
I hope that this research work will be of interest in the context of the product design to predict and determine the more appropriate operating parameters that may improve the hollow-cone spray performance.
