Charged particles build the mathematical model of multiphase turbulence
Equations: continuity equation of fluid plastic + (p) = S ( OtOx, J, charged particle continuity equation + () = 5 (9), the mixture continuity equation Sin (p + Zp) + (pvj + Zp , v,[link widoczny dla zalogowanych], j) = 0 (10) the fluid phase momentum equation (pVi) + go (pVjVi) a test + oath + + Σ (a) + S + F (11) PJrp momentum equation of charged particles (viruses (ppvpjvp1 ) consummation of marriage + vend + a (a) + Sp + Fp'M-Ei9: (12) where 9: is the apparent two-phase control volume amount and the actual charge-mass ratio of droplets to be distinguished.

F for the Magnus force, viS momentum for the phase change caused by the source term. 3 charged particles turbulent multiphase flow equations are used for single phase flow equations for the instantaneous Reynolds expansion method, the decomposition of the transient components were too volume and pulse volume, that is to take PP + P,[link widoczny dla zalogowanych], = +,[link widoczny dla zalogowanych], vj + np = np + n'p, = + 'pi, Vpj = Vpy +' PJp = m'p + mp will be charged the instantaneous particle conservation equation ( 9), (12) into P = npm started and will be divided by the m,[link widoczny dla zalogowanych], have the form of particles the instantaneous conservation equations: + (npVpj) = 0 (14) OtOx,, + poison (npv ~ vpi + + chu + a Fp, ~ i-Eng (15) H'p ¨ 'p-type (15) overlooked the internal pressure of charged particles and the viscosity, and qpn, so = Ertpg the time-averaged and fluctuating values into the gas phase and the Netherlands equations of particle phase power, further the average, and remove both the amount of time the average number of charge can be turbulent multiphase flow equations in time are: the fluid phase continuity equation + go (JD) = a beetle () + s a Σ (16) charged particle continuity equation O State pp0 (s a drug () + F Tuo + △ pg. + Σ + viS + F ~ A Sin (p + +) + Σmp / 'a) a Σn a ΣnF drugs + other + Fp, Mi-Einpqpm a poison + pmpdf'! two! a npmp-npnmp one ---- one hundred and eleven pv (20) (16) ~ type (20) formed a turbulent two-phase or multiphase flow of charge the most general mathematical model. 4 Conclusion two-fluid multiphase turbulence model theory, the particle phase as a fluid continuum that is intended to introduce the electric field on charged particles interaction term, the use of the average method described charged particles constructed a mathematical model of multiphase turbulence. equations taking into account the description of turbulence and electric field coupling, where any 'pEg. term describes the electric field pulse on the role of particle phase. The model of the fluid of charged particles to be more accurate mathematical model of turbulence.
