Resumo
A mathematical model of the hydrocarbon fuel channel flow taking into account coke precursor deposit formation on the walls of aeroengine cooling systems and chemical transformations in the gas phase is presented. The model is based on the Navier—Stokes and Maxwell equations in the electric potential form. The description in the form of a radical-chain mechanism is used for the partial liquid-phase oxidation of hydrocarbons. The effect of the electric field intensity (E = 100—2000 V m–1) on the formation of coke precursors at different temperatures of the channel walls Tw is shown. The calculations in the range of wall temperatures 350 < Tw < 600 K showed that the temperature was the major factor affecting the deposit intensity. The influence of the electrostatic field on the deposit intensity is significantly lower: the difference in the weights of coke deposits for the variants with E = 0 and E = 2000 V m–1 differs by 10% on the average.
