Effect of electric field intensity on electrophoretic migration and deformation of oil droplets in O/W emulsion under DC electric field: A molecular dynamics study

New insight into the role of the self-assembly of heteroatom compounds in heavy oil viscosity enhancement

“…Furthermore, understanding the arrangement of asphalt molecules is of significant importance in studying viscosity in crude oil systems as it provides insights into the molecular packing and intermolecular forces governing flow behavior, contributing to the development of strategies for viscosity control and optimization in oil production processes. [52][53][54] Subsequently, the aggregation structures of asphaltene molecules were further investigated, as shown in Fig. 6.…”

Study on microstructure evolution of waxy crude oil emulsions under dynamic cooling conditions

“…Sun 36 conducted experimental investigations on the viscoelastic and yield behavior during emulsion gelling process, elucidating the underlying mechanism through comprehensive analysis of experimental results. Furthermore, the collision and aggregation 37,38 of water droplets in the oil-water phase under external conditions such as shear 39 and electric eld 40,41 can be quanti-ed using statistical approaches like assessing the collision frequency and agglomeration efficiency of water droplets. [42][43][44] Subsequently, it can be utilized to forecast alterations in dynamic behavior 45 of water droplets within the system induced by microscopic phenomena like collision and aggregation, which holds immense signicance for further exploration of multidimensional behavioral characteristics exhibited by waxy crude oil emulsions.…”

Surface charging and electrophoretic behavior of conductive polymer micro-droplets in conductive polymer liquid solutions

“…Qi et al conducted a comprehensive investigation on the impact of the intensity of the electric field on the migration/deformation of oil droplets in a water medium. 29 It was observed that the oil droplet moves towards the negative electrode of the DC power supply. Moreover, it was observed that the extent of droplet deformation exhibited a direct correlation with applied electric field's magnitude.…”
