Abstract

Technical and scientific literature widely deals with the fundamental aspects and the physics of impinging jets. The usage of this kind of flow is very common in many industrial applications to realize heat and mass transfer toward the impinging surface since the process owns high efficiency and speed. Furthermore, an appropriate control of the flow permits to hit inaccessible zone of the material inside complex machine assemblies.

The importance of these aspects rise the attention of engineers and researcher who put a lot of attention in optimizing the shape of nozzles, the management of the discharge flow and the interaction between the orifice and the impinging surface.

Nevertheless, when it comes to design components engineered to leverage the characteristic of the impinging jets, many efforts are spent to adapt the basic system “nozzle-impinging surface” to the necessities of the process which has to be realized.

For this reason virtual campaigns with the usage of CFD are of vital importance during the design of systems and components typically used in the packaging industry.

This work focus on the optimization and study of nozzles for flow impingement used in the sealing and drying processes applied to the manufacturing of packages for liquid food products. The advantage earned using CFD technique permits the increasing of filling machines’ performances and, consequently, their productivity.
