Deformations of Soap Bubbles in a Uniform Electric Field

Sébastien Mawet, Hervé Caps, Stéphane Dorlobo

GRASP Lab, CESAM Research Unit, University of Liège, 4000 Liège, Belgium

Experimental device

camera DC generator light diffuser insulator aluminium plates bubble 1 cm

Reference

[1] TCR. Wilson, G. Taylor, The bursting of soap-bubbles in a uniform

electric Field, Math. Proc. Camb. Phil. Soc. 22, 728 (1925).

Deformation cycles

d ΔV = 1kV ΔV = 2kV ΔV = 3kV ΔV = 4kV

Hysteresis loop

Appearance of an hysteresis loop x t

Hysteresis due to the

movement of the contact line?

Context

Taylor (1925) [1] Present studies

Study of bubble deformations under the Taylor’s cone threshold.

Conclusion

We obtain a scaling law in good agreement with the experimental measures.

We need to investigate the effect movement of the

triple line on the bubble deformation.
