Numerical analysis of coalescence motion of droplets in oil under CPPM electric field
In this work, the coalescence motion characteristics of two droplets under the chaotic pulse position modulation (CPPM) electric field and the influence of electric field parameters on the coalescence motion of the droplets were studied. The numerical results show that the coalescence motion of the droplets under the action of CPPM electric field is related to the deformation relaxation time. The pulse width mainly affects the droplet movement process, and has little effect on the droplet coalescing time. The electric field strength affects the droplet coalescence efficiency, and the greater the electric field strength, the shorter the droplet coalescing time. This study provides a theoretical basis for the application of CPPM electric field in practice.
