Generation of spherical microscopic samples with single droplet solidification (U01)

金属熔体的单液滴过程提供了产生球形微量样品的可能性，以实现高通量。通常情况下，在静止的气体气氛中自由落体时会发生凝固。在这个项目中，将开发新的冷却条件，使用可变气体大气的并行流和液滴撞击后的传导换热。将评估液滴形成后的液滴振荡，以现场确定表面张力。

Single droplet processes with metallic melts offer the possibility to generate spherical micro samples for high throughput. The solidification takes place conventionally during free fall in a stagnant gas atmosphere. Within this project, new cooling conditions will be developed using a concurrent flow with variable gas atmospheres and conductive heat transfer after droplet impact. drop oscillations after droplet formation will be evaluated to determine the surface tension in-situ.
