Effect of a rotating magnetic field on the decay of a free‐falling metal jet

Abstract

Additive manufacturing enables the production of individualized high-grade components. Established techniques can use metal powder as its basic material. The generated product is often limited by the particle size distribution, particle shapes, and its composition. The metal powder manufacturing process needs to be understood and improved to enhance the quality of the fabricated products. In this work, numerical simulations are performed to describe the flow processes of powder production using the method of free-falling gas atomization. Furthermore, the use and influence of a rotating magnetic field is adapted to the atomization process and investigated by varying the influencing parameters like magnetic field strength and rotational frequency.
