    Tematy:
    electrostatic micro-actuator
    Laplace equation
    higher-order finite element method
    Opis:
    Comparison of several types of electrostatic micro-actuators is carried out, particularly with respect to their resultant force effects. The continuous mathematical model of such actuators is mostly described by the Laplace equation. In this paper, its numerical solution is performed by a fully adaptive higher-order finite element method, using a code developed by the authors. The methodology is illustrated by typical examples whose results are discussed.

    Opis:
    Simulation of movement of a large number of charged particles in external electrostatic field is of great importance for a correct design of separators whose aim is to select them according to the sign of their charge. The paper deals with modeling of their trajectories in a specific arrangement consisting of a profile vessel equipped with two electrodes and several collecting bins. Electric field between the electrodes is determined using a fully adaptive higher-order finite element method. The movement (velocities and trajectories) of the particles affected by electric field, gravity and aerodynamic resistance is modeled by an adaptive Runge-Kutta-Fehlberg method with an appropriately varying time step. On the other hand, their charges are rather low, so that it is possible to neglect the Coulomb forces acting among them. The methodology is illustrated by a typical example whose results are discussed.

    static characteristic
    Opis:
    An electromagnetic valve for control of flow of electrically non-conductive liquids is proposed and modeled. The device contains only one movable part (a cylindrical plunger) whose movement is controlled by a secondary magnetic circuit with a high-parameter permanent magnet and current in the field coil. The paper presents its mathematical model that is solved numerically. For computations we used our own code Agros2D based on a fully adaptive higher-order finite element method. The static characteristics of the device are calculated using a modified version of the Eggshell method in order to avoid undesirable peaks and oscillations. The principal results are evaluated and discussed.
