N2 - 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.
