Abstract:

This research uses a computational fluid dynamic model to simulate motion and deformation of a dielectric drop in electrolyte solution in a microchannel. Wall charge density, the Debye-Hückel parameter and the Weber number are varied for uncharged, positively and negatively charged drop interfaces. Drop flow and deformation were analysed and the effects of charge distribution, electric field and permittivity jump were discussed. For a positively charged channel wall, negatively charged drops moved faster and positively charged drops moved slower than an uncharged drop. This effect increased fo

Abstract:

An asymptotic calculation of a dipole electromagnetic radiation of an uncharged conductive drop oscillating with a finite amplitude in an external electrostatic field to within the second order of smallness inclusive on the relation of the amplitude of oscillations to the radius of an initial drop is carried out. It is shown that the first mode of oscillations is excited in the calculation of the second order of smallness. As a result, the centers of the induced charges with different signs will synchronously oscillate, and the drop will radiate electromagnetic waves of dipolar type, forming t

Abstract:

Nonlinear asymptotic calculations for two small parameters (the size of the dimensionless stationary deformation of an initially spherical drop and that of the dimensionless amplitude of its capillary osсillation) were used to analyze the electromagnetic radiation of an uncharged drop oscillating in an electrostatic field. In the external electrostatic field, on the top of the drop, electric charges of the opposite signes are formed and the “effective” charges on the axes of its symmetry can be assigned to them, respectively. As the distance between those “effective” charges is of the order of

Abstract:

Contact, induction, and corona electrostatic charging systems for pesticide spraying are reviewed and are compared with uncharged spraying systems. When uncharged sprays are poorly intercepted by plants, charging significantly increases deposition, drawing from the reservoir normally deposited on the soil. Post-emergent herbicide spraying is the one area where the benefits of electrostatic charging are identified least easily. For insecticides and fungicides where the young crop is the ‘general’ target, increased capture of charged spray may permit reducing doses with economic and environmenta

Abstract:

The oscillations of an uncharged spheroidal drop of a conducting liquid in a uniform electrostatic field are considered. It is shown that the oscillations of the centers of inducting charges of different signs connected with the surface oscillation lead to the radiation of electromagnetic waves of the dipole type. A mathematical model of the electromagnetic radiation is constructed and an assessment of its intensity depending on the size of a drop and on the external field strength is carried out.

Abstract:

The electrohydrodynamic instability of the charged liquid surface manifests itself in the instability of a highly charged drop, the instability of charged drop in superposition of external electrostatic field and gravitational field, as well as the instability of flat charged surface of electroconductive liquid. Attempts to experimentally verify the correctness of the criterion of electrohydrodynamic instability of a highly charged drop, derived by theoretical methods a hundred and a half years ago, by the Rayleigh criterion, which began in the middle of the last century and continues to the p

Abstract:

We consider a neutrally buoyant and initially uncharged drop in a second liquid subjected to a uniform electric field. Both liquids are taken to be leaky dielectrics. The jump in electrical properties creates an electric stress balanced by hydrodynamic and capillary stresses. Assuming creeping flow conditions and axisymmetry of the problem, the electric and flow fields are solved numerically withboundary integral techniques. The system is characterized by the physical property ratios R (resistivities), Q (permitivities) and λ (dynamic viscosities). Depending on these parameters, the drop defor

Abstract:

An experimental investigation was conducted to determine the secondary breakup morphology of electrically charged drops. Movies of drop breakup in a high speed air stream were recorded for drops charged between 0 and 60% of the Rayleigh charge limit. The conventional Weber number was found to be insufficient to classify the breakup morphology of charged drops. Rather an electrostatic Weber number was defined to account for the presence of the electrostatic surface stress. When the electrostatic Weber number was used in place of the classical Weber number, the observed breakup morphology was fo

Abstract Crack extensions in small side-grooved arc-shaped tension specimens of uncharged and hydrogen-charged conventionally forged 21-6-9 stainless steels are simulated using two-dimensional plane strain finite element analyses with the nodal release method. The finite element analyses are conducted with the input crack extension-displacement curves from the experiments. The crack extensions are simulated by releasing the nodal points ahead of the initial crack tips. The crack extensions follow the experimental results based on the electric potential drop method.
