Аннотация:Theoretical asymptotic calculations linear with respect to small dimensionless amplitude of oscillationshave been employed to study the influence of the viscoelastic properties of a charged droplet of anelectrically conducting viscous liquid on the intensity of its electromagnetic radiation. It has been shown thatallowance for the effect of viscosity relaxation leads to a decrease in the damping decrement value, which isdetermined by energy losses for electromagnetic wave emission, and the intensity of high-frequency electromagneticradiation; a substantial reduction in the viscous damping decrement of small cloud droplets; and anessential dependence of the viscous damping decrement on the characteristic relaxation time. It has beenfound that the viscosity relaxation of a liquid has no significant effect on damped capillary oscillations andelectromagnetic radiation of rain droplets. Viscoelasticity and viscosity of the liquid do not influence the conditionscritical for the realization of the electrostatic instability of a droplet with respect to its own charge.
