Study of leaky dielectric droplet behavior under an electric field: effect of viscosity and electric conductivity ratios
In this research, hydrodynamic behavior of a leaky dielectric droplet under an electric field is simulated. The level set method is used for interface tracking and the ghost fluid method is used for modeling discontinuous quantities at interface. Using Taylor’s leaky dielectric model, electric field and electric force at the interface is calculated. Simulation results show the droplet deformati...
متن کاملElectrical Actuation of Textile Polymer Materials
Polymers used in textiles were found to be effective as actuator materials with large deformation. Particularly, the polymers with low dielectric constants used to be considered inactive to electric field were turned out to be efficient actuator materials. They were classified into three types; (1) polymer gels swollen with solvents, (2) plasticized polymers, (3) bulk polymers. From the viewpoi...
متن کاملElectrical properties of UHMWPE/graphite nanoplates composites obtained by in-situ polymerization method
There are described nanocomposites based on ultra high molecular weight polyethylene and graphite nanoplates prepared by in-situ polymerization method. It is carried out a comprehensive study of electric properties of these composites, including direct current (dc) and alternating current (ac) properties. There is explored dependence of the conductivity and dielectric permeability on filler con...
متن کاملTuning of whispering gallery modes of spherical resonators using an external electric field.
In this paper we investigate the electrostriction effect on the whispering gallery modes (WGM) of polymeric microspheres and the feasibility of a WGM-based microsensor for electric field measurement. The electrostriction is the elastic deformation (strain) of a dielectric material under the force exerted by an electrostatic field. The deformation is accompanied by mechanical stress which pertur...
متن کاملPhoto-induced deformation of azobenzene polymers: theory and simulations
A microscopic theory is developed to describe light-induced deformation of azobenzene polymers of different chemical structures: uncross-linked low-molecular-weight azobenzene polymers and cross-linked azobenzene polymers (azobenzene elastomers) bearing azobenzene chromophores in their strands. According to the microscopic theory the light-induced deformation is caused by reorientation of azobe...
