Abstract:
Three-dimensional computer simulations of the dynamics of sessile droplets in an
electric field and without it are carried out on the basis of the lattice Boltzmann method
(LBM). The dielectric droplets are placed on the surface of the lower electrode. The electrical
and hydrodynamic parts of the problem are solved simultaneously. After application of an
electric field, the droplets begin to lengthen in the field direction. The contact angle is
measured after the droplet acquires its equilibrium shape. It is shown that the contact angle
slightly increases with increasing the electric field due to electrostatic forces. Above a certain
critical value of the electrical Bond number, the droplets cannot acquire a stable form, the
elongation becomes unlimited, and the droplets are destroyed.
