In this work, mathematical modeling of the motion of charged microdroplets with diameters of 30 and 100 μm under the combined action of electric and gas-dynamic fields is carried out. The structure of the electric field was determined by a system of coaxially located liquid and gas spray capillaries and an annular transport counter electrode. The diameter of the hole in it ranged from 15 to 21 mm; electric potential on capillaries from 2.4 to 5 kV. The pressure excess of the gas at the inlet to the capillary system over the atmosphere ranged from 1 to 6 atm. The numerical integration of the system of Navier-Stokes equations was carried out using the ANSYS Fluent package in an axisymmetric formulation without taking into account the space charge of the droplets. Keywords: electrospray, transport counter electrode, charged microdroplets, numerical modeling, ANSYS Fluent.
