Effect of electrostatic forces on the dispersion of like-charged solid particles transported by homogeneous isotropic turbulence

The effect of electrostatic forces on the dispersion small like-charged inertial particles transported by a homogeneous isotropic turbulent flow is analysed means direct numerical simulations coupled with Lagrangian tracking charged particles. results show that particle decreases for increasing charge. Since related to intensity agitation and integral time scale, we analyse effects these two quantities. Particle In fact, kinetic energy not directly modified forces, which are conservative, it rather entrainment fluid turbulence modified. To support this claim, one shows fluid–particle velocity covariance destructed destruction can be predicted drawing an analogy between inter-particle collisions Coulomb collisions. As expected, decorrelate velocities leading decrease scale. Finally, allows us predict reduction dispersion.
