Bubble Formation in Microgravity with and without Electric Fields

a) Shape of a bubble injected into a liquid in microgravity and b) the influence of the on the bubble shape at detachment. The electric field magnitude increases from left to right in b) leading to c) decreased bubble volume and increased elongation. Former postdoc Dr. Estelle Iacona and Prof. Cila Herman studied the influence of electric fields on bubble formation in microgravity in a NASA sponsored research project.
