What is it about?

The aerodynamic characteristics of two impinging jets play an important role in the melt-blowing process to form micro/nanofibrous filters. We have shown for the first time that the unique characteristics of the dual-impinging jets under the slot-die nozzle for controlling the melt-blowing airflow field.

Why is it important?

The interaction of two impinging jets is important in the melt-blowing process. The experimental work helps to gain a better understanding of the dual-impinging jets produced by the slot-die nozzle and to establish a quantitative description of the jets. Thus, not only valuable scientific information but also knowledge that could be used directly in practice are provided.

Perspectives

We hope this article makes what people might think is a boring, highly specialized area like fluid dynamics and fiber processing kind of interesting or maybe even exciting.
