[SLPC12-01] Temperature and surface tension of laser-induced falling drops

*Joerg Volpp¹ (1. Luleå University of Technology)

Both the falling drop and surface wave analysis were used to determine surface tension values in this work. Surface waves could be related to the surface temperature, which gives high temperature surface tension values. By measuring the surface tension of a falling drop and comparing this value to the determined relation from the surface wave analysis, the surface temperature of the drop could be indirectly estimated.
