OsciJet Nozzles

OsciJet Nozzles are based on the principle of fluidic oscillators. These devices create a self-induced oscillation without requiring any moving parts. The oscillators are scalable to any size (diameter of up to several cm) and work at frequencies ranging from a few Hz up to several kHz. Furthermore, devices are available which do not create a sweeping motion but pulsate in the main jet direction. OsciJet nozzles can be used with input pressures from several millibars up to >200 bar using various types of fluids. Besides, it can be manufactured from various materials.

What is the result? Up to …

• … 15x better mixing
• … 10x better cooling
• … broader distribution
• … constant spray angle over the whole pressure range

Whether hairspray or diesel engine, the generation of fluid spray is often required. Every process has its own requirements for the size of the generated droplets. However, they all have in common that the distribution of the droplet size should be as homogeneous as possible. Due to the sweeping motion of the jet, the OsciJet nozzles produce a strong shear which results in uniform droplets. Therefore, the OsciJet nozzle can provide smaller and more homogeneous droplets in comparison to a conventional nozzle. The droplet size can be regulated by the sweeping frequency.

The effective surface area of a cooling air jet is important for the cooling of electronic parts or even engines. Here, a dynamic jet can yield a significant increase in effective surface area covered by the cooling fluid. Thereby, the efficiency is improved and a smaller cooling mass flow is required. Furthermore, difficult to reach place can be cooled more effectively.
