NASA's innovative rocket nozzle paves way for deep space missions

NASA recently built and tested an additively-manufactured—or 3D printed—rocket engine nozzle made of aluminum, making it lighter than conventional nozzles and setting the course for deep space flights that can carry more ...

Elastic nozzles could create more stable liquid jets

Until now, little attention has been paid to the flow of liquid through deformable elastic nozzles. New research published in The European Physical Journal Special Topics introduces the concept of passively-deforming nozzles, ...

Microfountain pen draws minute patterns for live cells, circuits

Advances in intuitive microwriting devices that can print microstructures could pattern electric circuits and more. The setup, featuring a robot arm to hold the micropen, deposits ink onto the surface, much like writing by ...

Spray drying—perfect dosing thanks to drug capsules

Instant coffee and powdered milk are produced by spray drying. Fraunhofer researchers have adapted this technique to the tricky question of incorporating insoluble substances in core-shell particles. The new method helps ...

Nozzle

A nozzle is a device designed to control the direction or characteristics of a fluid flow (especially to increase velocity) as it exits (or enters) an enclosed chamber or pipe via an orifice.

A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas). Nozzles are frequently used to control the rate of flow, speed, direction, mass, shape, and/or the pressure of the stream that emerges from them.
