  - Year 2018

  The dynamical projectors method proves to reduce a multicomponent problem to the simplest one-component problem with its solution determined by specific initial or boundary conditions. Its universality and application in many different physical problems make it particularly useful in hydrodynamics, electrodynamics, plasma physics, and boundary layer problems. A great variety of underlying mechanisms are included making this book...

• Suitability study of hybrid model of electrodynamic actuator

  Publication

  - Year 2014

  This paper presents the proposal of the hybrid circuit-field model of an electrodynamic actuator. The field model uses the inductor current as the input data which is obtained from the circuit model or experimentally. The field model implemented using the FLUX program makes it possible to easily determine the pressure distribution acting on the disc. The results have been verified experimentally.

  - ENTROPY - Year 2021

  In this paper, the formulation of time-fractional (TF) electrodynamics is derived based on the Riemann-Silberstein (RS) vector. With the use of this vector and fractional-order derivatives, one can write TF Maxwell’s equations in a compact form, which allows for modelling of energy dissipation and dynamics of electromagnetic systems with memory. Therefore, we formulate TF Maxwell’s equations using the RS vector and analyse their...

  - INTERNATIONAL JOURNAL OF APPLIED ELECTROMAGNETICS AND MECHANICS - Year 2019

  Electrodynamic actuators are used in hybrid switching systems where a very quick contact separation as well as operation repeatability and long-term reliability are required. The article presents selected results of thermal studies in the electrodynamic drive system. Study was carried out on the basis of the 3D electromagneto-thermal model implemented in the Ansys_Maxwell environment. The present model allows to determine the critical...

  - Communications in Nonlinear Science and Numerical Simulation - Year 2024

  In this paper, control engineering methods are presented with regard to modelling and simulations of signal propagation in time-fractional (TF) electrodynamics. That is, signal propagation is simulated in electromagnetic media described by Maxwell’s equations with fractional-order constitutive relations in the time domain. We demonstrate that such equations in TF electrodynamics can be considered as a continuous-time system of...

  - Year 2004

  W artykule przedstawiono skutki oddziaływania sił elektrodynamicznych w układzie szyn zbiorczych rozdzielnic podczas zwarć metalicznych i łukowych. Przedstawiono metodę obliczania ugięć i naprężeń w szynach od sił elektrodynamicznych. Opisano wpływ łuku zwarciowego na zwiększenie sił elektrodynamicznych działających na szynę skrajną. Omówiono wpływ rezystancji niskonapięciowego łuku zwarciowego na ograniczenie pradów zwarciowych....
