NOT KNOWN FACTS ABOUT MICRONEEDLING SPARKS

The substantial-speed jet upon bubble floor impression (2000 m s−1 by BEM) was similar to the earlier described values (2200 m s−1 for ALE and 2250 m s−one without cost-Lagrange). Even so, in BEM, the model is based on probable circulation. There was no travelling or mirrored shock wave inside the bubble. However, the simulation captured most
